Dye from ring felt - discoloring white OTA !!!
      #5645060 - 01/26/13 08:17 PM

I removed the rings on my AT 106 the other day and discovered that the dye from the felt had left a faint bluish tint on the OTA. I tried to use car polish to get it off but it would not come out. I suppose it is no big deal since the rings will always be there, but it is pretty annoying. I am guessing that the felt got wet the last time I viewed in heavy dew.

I immediately went and bought some white velcro and threw away the loop part. Then I took the soft part and replaced the black felt on every one of my refractor's rings. I replaced not only the tube ring felt but also the felt that allows the dew shields to slide over the OTA.

Live and learn.

Sorry to hear that. How long have you owned this AT refractor?

My 106LE rings use rubber instead of felt... Your 106 is the standard 106?

Wow; glad I read your post; I'm now going to replace my black felt on my rings with white, to protect my white Vixen!

Thanks for the warning!

I've seen the same thing on my light colored Meade OTAs . Like you said , not a big deal because the rings stay put and the discoloration won't be seen , so I left it alone . I'm surprised that the car polish didn't work as that would have been my first suggestion for a remedy . More like a slight yellowing is what it's done to mine and these have never seen heavy dewing . Just pigment transfer I guess .

I would be curious as to how a little WD40 would work. It cleans a lot of unusual things.

I would strongly discourage this . Depending on the paint , you could suffer a complete meltdown .
If it won't buff off with a good car wax or cleaner wax , it ain't comin off .

OK if you say so, but it has done no harm to the paint on my car the couple of times I have used it. Not sure what the chemical reaction is that you are referring to but I will take your word for it in case it ever comes up.

I had a similar thing happen with a brand new AT 80 from a few years ago. I pulled it out of the case and was thrilled at how beautiful it was/is. Then I moved the dew shield out and to my horror, there were black stains on the tube. It was from the felt under the shield to keep it in place. The stains came right off with Windex and did not harm the beautiful white tube finish. Whew! I was elated. So I removed the shield and replaced felt pieces with white felt. I have also replaced all felt on every ring that I own. I replace ring felt often to simply cover more completely.

Best, Linda B.

Humm..

I have been using WD-40 to clean grimy parts of some pretty nice bicycle frames for 25 years without a problem.

This what the WD-40 Website:

"What surfaces or materials are OK to use WD-40 Multi-Use Product on?

WD-40 Multi-Use Product can be used on just about everything. It is safe to use on metal, rubber, wood and plastic. It can also be applied to painted metal surfaces without harming the paint. Polycarbonate and clear polystyrene plastic are among the few surfaces on which to avoid using a petroleum-based product like WD-40 Multi-Use Product."


By the way, WD-40 also works great for cleaning pine pitch off your hands.

Jon

I use wd-40 all the time on my mount and pier that are left outside under a 365.. displaces water well, hampers rust formation, great cleaner.. but as they say.. test on an conspicuous spot first.

Mine is the AT 106 not the AT 106LE. And as I recall it did not come with rings I bought the ones suggested by Astronomics to fit the scope.

I have owned it for about 2 years but have never removed the rings before so I really don't know when it happened or how long it took to happen.

Anyway I suspect it was just some cheap dye used in the felt and I would hope not to many other rings use that particular felt.

You could also try white vinegar.

Or a paper towel dipped in bleach on an inconspicuous part of the stain. Just dab, no rubbing.

I had the same problem with my old AT106. It appeared after an especially dewy night. Tried as I might, couldn't get it removed. Didn't try wd40 though...

I am not touching mine, Polish did not remove it so I know this dye has gone deep into the paint, I am just leaving it alone now. It is not very noticeable anyway, and with the rings attached as they always are then it is not seen at all. I would never sell this scope anyway so it doesn't matter to me, but I know many of you sell and buy scopes like they are trading cards and I wanted you to be aware of this issue.

Lane,
One remedy I've found for grape stains on the counter, coffee stains around the sink, is 409. I've used it to clean a number of things over the years. I use a warm soapy cloth afterwards if I'm concerned with leaving it on a surface followed by a wipe down with a clean, wet cloth. Never used it on OTA baked enamels though but compared to vinegar or bleach, it would seem to be a less caustic solution? Just a thought ...

409 is good stuff along with a variety of other all purpose cleaners , but I believe the situation at hand is a colored stain that has been obsorbed into the painted finish and is no longer a surface stain . Once this pigment is saturated deep inside the painted finish it would require digging down in to get it out . A good automotive cleaner wax will take a small bit of surface material away cleaning a stain that hasn't penetrated deep into the surface , but if this hasn't worked , anything aside from sanding the paint to the depth of the stain will be a lost cause and unless one wants to re paint the tube , the stain is there to stay .
A good Sun bleaching might work , but who knows how long that might take .
If the tube ring cover the discoloration , what difference does it make ?

PS: I cant seem to get the hang of quotes inside of quotes. It gets all jumbled up when I try it.
