Terrified of Cleaning Corrector
      #6046815 - 08/26/13 11:31 AM

My pride and joy C9.25 needs its corrector cleaned. It has pollen on it. It is not a lot, but I know it needs to be removed. I am actually more 'petrified' than 'terrified' at the thought that I could scratch it or damage it. I've tried a blower brush, and it does nothing.

I know pollen is 'grainy,' so I can't see how I can remove it without scratching, since it won't blow off. I know that others say to use windex and lens papers, or alcohol with a little Dawn. I just can't seem to overcome this fear that I will mess it up. It is so little that it doesn't effect the view, but I know it is damaging if left on the corrector.

It's really not that scary. I bought this kit and it works just great! Just follow the instructions and you'll be good to go. Just so you know, the coatings on a corrector are quite robust, kinda' like your eyepieces. It's not like cleaning a mirror.

Yes I just did mine with a home made solution of mostly distilled water and a little Windex & isopropyl alcohol cleaned with a microfiber cloth. Looks real nice now and even passes the flashlight test.

Go to an art supply house, buy a wide flat white nylon Loew Cornell Artist brush. I am being specific about the brush because the white nylon brushes are very soft and will not scratch your corrector. Clean the brush with dish detergent and water and let dry thoroughly. Take said brush and while using a blower bulb gently brush off and blow the pollen away.

Then clean using a recommended procedure. That's how I do it.

Don't worry! Despite the recommendations of Doc Clay's method, and using several other methods, I've concluded that if you're really picky like I am, it is IMPOSSIBLE to get a corrector back to day-1 levels of cleanliness. Every method I've ever used, and I've used most of them, has left residues of some kind on the corrector. Around the secondary and at the edges are particularly hard to get clean.

My advice - do the best you can. Don't expect perfection. Use and enjoy the scope no matter what results your method returns. As long as you use a soft brush and blower bulb to dislodge any big pieces, you're no going to hurt the glass or coatings using any modern cleaning solution - Zeiss, ROR, Pursol, etc.

Regards,

Jim

I just cleaned my C9.25 a month ago. I also used the same kit as David. I clean my corrector about once every two years, depending on the pollen seasons of that year. I've gotten so good I can clean it and dry it within 20 minutes now.

Thanks guys! I'm going to do it this weekend. It's been in my observatory and my new 80ed and 102gt are arriving this week to go in there as my viewing/photography setup. So I need to clean the 9.25 before putting it back in its case. I think I like the sound of the Televue method as it minimizes touching. Have any of you used this method? I'll report back after I do it.

A bit over a year-ago when I resurrected my interest in Astronomy, I had my 1993 Celestar C-8 sitting in a box for nearly 20 years... the corrector had gunk and the primary also had something growing there... Luckily, fellow CN member "Orion61" offers a cleaning service for a very low and reasonable price. I shipped it to him, he cleaned it, re-greased my focuser and flocked the inner tube. My Celestar C-8 has excellent optics and its like brand-new. I would never want to take it apart, but then again I am all thumbs... My advice, send it to Larry...

Some 600 grit wet sand isn't too bad. What I do for around the edges is get a handful of cotton swabs and as you sweep around the edges with the swab, rotate it. I said a handful and that's because when I do it, I allow one rotation of the swab and toss it. An 11" SC takes a LOT of swabs.

Jim, I agree totally. For some reason, and despite vigilant efforts with various processes, it does seem impossible to get them back to factory clean. I really don't understand why that is nor why the flashlight test (which we should ignore?) makes us cringe. I've even tried to clean to the flashlight test standard to no avail. We love our optics, so such attention to them has a diminishing return way up the time and effort scale.

One thing I have read which makes sense but I cannot say I have examples as I have only cleaned one corrector. If you can be choosy do it on a day of low humidity or in an well air conditioned home and you well have much less streaking.

I agree with David. I've found the Q tip approach works well for the final stubborn small spots. I'll often combine it with breathing on the glass to fog it up slightly prior to the final Q tip wipe.

It makes it fairly easy to eliminate most cleaning spots.

Jim, good advise and sure would like to get it like the day I got it, but can see it ain't gonna happen. I would also like to get rid od all those little spots from the dew. Unfortunately I waited too long to get a dew shield at first and went through to many dew cycles.

As far as Zeiss goes, can I use those little wipes they have, works great on my glasses?

I will soon have to address the numerous water spots on my nearly new C-14 corrector to improve my prevailing, ongoing daily mood.It is a long story but I was in the final stages of my initial All-Star Alignment procedure- after two hours of restarts(center Altair in the eyepiece- a 2 minute procedure) when it suddenly clouded over. I was seeing glimpses of the bright star and hanging on until I realized that it started to rain in my observatory. So , that was a first for me! No harm done essentially but numerous H2O deposits were left all over on the corrector. I left it uncovered to dry and headed for bed at 2:30 AM a bit rattled.
Anyhow, after some research into cleaning ideas, I don't think Rolands' finger method with saliva is going to work; the scale of the deposits is too broad. I wonder if anyone has a word of advice on how to proceed working with a clean corrector and what cleaning solution might be more effective for these numerous tiny pin points that have invaded my glass?
Hijacking the thread a little but my motive is for the collective good.
Jerry

In my opinion after a few dozen corrector cleans and hundreds to thousands of other photography glass cleaning exercises, the best way to clean a corrector is the same as cleaning a mirror. Use mild dishwater detergent and running warm water and drain it on its side. Avoid touching it and swiping anything across it except to blot up excess water when you're done. You can leave the secondary attached, it's waterproof too.

I recently tired Doc Clay's solution and it did leave streaks on the corrector no matter what I did (the humidity was below the recommended 65%). Then I resorted to my secret weapon: acetone and the corrector is now good as new.

There is an application where Doc Clay's solution shines -- literally! -- : on my AR-coated flat-screen TV. Normally, this is impossible to get streak free but with the solution, and acetone for where my 3yo had smeared greasy food on it, it's as good as the day it came out of the box.

Statutory warning about acetone: use only a dampened tissue and never pour or spray directly on the optic. It won't damage the optic but will take paint off wherever it gets in contact with it such as on the retaining ring. Also, when wiping with acetone, lift off the tissue so that the remaining acetone is wicked off. If you don't do this, you can leave a residue from the acetone itself. Hardware store acetone is good enough.

Ok, just tried the wipes and they did pretty well an no residue left and finished with a micro cloth. It looks a lot better, but was not able to get the fine spots out. I guess it's too late as they probably have etched there way in the coatings.

Oh well, it won't hurt the performance any as they say and it does look a little prettier

"I recently tired Doc Clay's solution and it did leave streaks on the corrector no matter what I did (the humidity was below the recommended 65%). Then I resorted to my secret weapon: acetone and the corrector is now good as new."

Ironically, Tanveer, I was at the hardware store yesterday picking up a few last minute items for a roadtrip I embark on Saturday, and happened to pick up some acetone with the intent of using it to try and get the stubborn discolorations left over from past cleaning efforts off of the correctors of my C8 and C6. That's a Friday afternoon project. I was planning on applying the acetone with a sterile cotton swab.

Jim

The front corrector is a pretty tough beast, never managed to damage any coating yet either.

Small difficult spots likely need a bit of a soak to loosen them, a cotten wool bud is good for this.

I think I would be right in saying the front corrector is a lumb of plate glass cast into a mold. The outer surface will be ground flatter but not the inner as that needs to remain the shape of the mold. Take that into account and cleaning it should not really be hazardous.

1) Duct tape to remove the gross contamination.
2) Steel wool and turpentine for the stubborn spots.
3) Repeat as needed.
4) We want pics when you are done!


On second thought you received MUCH BETTER advice from the above posters.

On a serious note - please let us know how it turns out. Maybe some before and after pics?

Well I was terrified of cleaning my corrector once. And I was pretty terrified of replacing the CPU fan on my computer. But I have crossed those Rubicons. Sometimes you just gotta do what you gotta do.

It helps when the situation demands either a fix or tossing the equipment. Then, with nothing left to lose, you watch your youtube videos and "go bold." So when the CPU fan has come unhinged and the whole thing is down, you've got a pile of junk, so, go for it.

It's a little harder with a telescope because in the usual run of things they don't crash, they just degrade, because they're dirty.

It may sound gross, but saliva actually works pretty well. I used a q-tip just dabbed it on the tongue and made small, easy circles. Don't eat any Oreo cookies prior. Barring that, acetone does quite a good job. Same small circular q-tip technique.

You can't really remove the coatings, but be careful of scratches.

So, has anyone ever achieved that factory clean?

Here in west TX, there is so much airborne dust that I have to clean my corrector plate after every single session- and sometimes during the middle of a session! My preferred method is completely "dry." I put a hair drier (NO heat!) on the plate to encourage the dust to go airborne, and I very carefully brush the dust to loosen it with a lens-cleaning cloth. This method avoids the use of solvents, which are a last resort. Using something wet like isopropyl alcohol can leach out material from the dust/pollen/crud, leaving surface stains that will be really difficult to remove.

Distilled water and a few drops of liquid dish soap (not the kind for the dishwasher, but for the sink). My corrector hadn't been cleaned since I got it in 2001 and it started to look like someone puked on it! Put some of this solution in a spray bottle and liberally sprayed the corrector down, with the scope pointing down to keep water from seeping into the tube. Let sit for a few minutes but not too long as you don't want the water to start drying. Washed with distilled water. A few iterations of this along with using cotton swabs and balls for the more persistent clots and the lens looks almost as good as new!

I just spent a good 3 1/2 hours cleaning my C14 corrector. It's pretty darn close to factory I must say. I had a nice, hazy film over it from dew and dust. I also had a nice even coat of pollen. Pretty tough stuff to get off. I used filtered water and alcohol 50/50. I also used a high quality microfiber cloth (not the one that comes with it, this one is almost silky) to get almost every streak out. A LOT of elbow grease and a bright, focusable LED flashlight. I used a bandage gauze instead of a cotton ball... really because we had no cotton balls but I think the gauze leaves less fuzzies. You want to barely dip the tip of a wad of gauze in the alcohol/water and then ball the rest up around it to kind of distribute the mixture. Then, (I started at 12 o'clock on the corrector and worked counter clockwise only to later find out it would've been better to go clockwise) use the damp gauze to wipe down (from center outwards like bicycle spokes) to wipe away the pollen. Only go about an hours worth over (if the corrector plate were a clock). You will be able to feel when the pollen is gone because the strokes will become smooth and less "frictiony". Set the gauze aside and let the damp spot dry for say... 10-15 seconds. (The plate will be ugly in that spot... DONT. PANIC.) Fold the microfiber cloth in half. While holding the flashlight in one hand, use your finger (other hand) to wipe away the drying mixture from the center outwards (don't start wiping too soon or your cloth will become saturated) You will have to go over it MANY times to see the streaks gradually disappear. Use your flashlight at different angles to really highlight the streaks. Repeat until you get all the way around the corrector. Afterwards, go around the edges to get the hard to reach stuff. Just keep at it and take breaks when you need to.

I forgot to add... when using the microfiber cloth, I put about as much pressure on it as I would itching my eye. If that helps. Getting pollen off is a bit trickier than getting simple dust off. Afterwards, I used canned air from a safe distance (about 2 feet)to blow off what accumulated at the bottom of the scope. To take it a step further, I used a laser pointer to scan over sections of the corrector. If the red dot gets brighter, there is a smudge in that area.

I didn't read every post here but I use to detail out corporate jets where residue on glass was a flat out no-no. I developed a perfectly clean glass cleaning method used on all glass surfaces including the cockpit dials and heads up display...

I use alcohol with mere and I mean TINY drop of dawn in the entire solution. Next I cut it with 30% water. The water is only there to allow the solution to last long enough to float away dirt. Straight alcohol is too evaporative. I should mention I choose this solution over Windex and the commercial produces that come through the airport because it proved to have the least residue.

And residue: I've found it's either finger oils or soap or both together . My custom solution has its own but its less objectionable.

Now the cleaning method. When I cleaned the inside of jets I shut down all power. With the exception of the cockpit it was blacked out and the galley and John was a cave.

Next - out comes the mag light. Not only did it isolate the blemishes needi g attention it was ruthlessly clear wether or not I was successful in cleaning. This was a degree of cleaning that no charter customer/owner would ever notice but it was easy enough to do and it got me less flak than the other detailers. My secret was soon discovered but more in that in a second.

What became evident no matter how effective the solution was that you couldn't just chemical clean it away - you still had residue - far less than Windex but residue. It became imperative to go one step further to assure immaculate results.

Dry buff. I'd get a soft cottony cloth - certainly clean - and buff the haze and residue out of existence. I do the same for my telescope optics and oculars. In so e cases ill fog the glass with breath then buff. The results are immaculate.

But my secret got out...

The management caught me with the mag light in a dark plane wondering why I'd clean in the dark with a light when we had the juice hooked up to the bus. Well they figured out my technique and they loved it. And what do you do to a fella that's invented the best way to clean the glass on a 50 million dollar jet? You higher an appliance store clerk as your new boss to
chase after you with mag light in hand shutting down the power on all the jets and then critting you on it - even though it was a level if clean they could never detect in regular lighting.

I drove off and never returned.

I'm not saying that you should have a cavalier attitude about cleaning expensive optics but I make my living as a photographer for a daily newspaper and I have cleaned, with anything I could, dew, fog, whatever off a $6,000 Nikkor 300 f/2.8 many times while shooting high school football in the sweltering Florida summer heat and I have never damaged the coatings. Optical coatings are pretty tough. Just don't obsess with making them factory clean. Ain't gona happen ,as another poster said, Get stuff off that can damage the coatings and live with some residue from the cleaning process and be happy. And never look at the optics on anything with a flashlight!!!
