If you want you can take a look at my webshop here: http://shop.collimated.com.
All international shipping is done with FedEx that allows the First Contact Polymer products to be shipped in small quantities (<10 bottles).

I have found that the back of a sticky note works. any low grade adhesive will work. In LP restoration, I use elmers glue for instance. In fact any low grade adhesive will work, best would be low quality/adhesion silicone polymer that dries on contact with oxygen. peel off n Wah Lah. Dont forget the other contact stuff maybe another repackaged chemical. I do have access to a Gas Chromatagraph... Worth a looksee.

Two other ideas: acetone on lens tissue, drop it while wet onto the mirror, drag gently off it. Repeat if needed, different clean bit every time. Other idea: there's a liquid rubber used for resisting soldering flow onto bare metal. As it won't react with the metal, even with the heat of soldering, and peels off easily after it's cured, heated or otherwise, it is likely safe on glass. It might cost more than it's worth, and you'd do well to examine its data sheet. It's supposed to have a short shelf life, but I have some now in 2013 with a use-by date of week 33 in 2007, but it's as fresh as a daisy. Not sure who makes it, but it's "latex solder resist".

First Contact is a mixture main of Collodion and a few other polymers. The Nitrocellulose and the Ether derivative make it difficult to ship by air.

Traditionally we use sterile glue free cotton throat swabs with wooden sticks (Puritan Brand) and methanol for scanner mirrors. Acetone is used when you have finger prints or grease.

The other technique is to fold a high grade lens tissue and clamp it in hemostat, wipe once or twice when wetted with methanol, and discard.


The trick is getting good grade chems that are not denatured or have water in them. That leaves a white film if either is present.


First contact is just a high end option, mainly used for large optics in industry.

... you should get similar results to "First Contact" with a mixture of acetone and latex - acetone solves all organic residues and the drying/polymerising latex will 'fix' them inside the matrix, so you can peel it off ...

Actually, best forget the latex... I tested it on clean polycarbonate, fresh out of maker's protective film. Also, clean acrylic, and an MgFl coated lens. In each case no damage results, but it leaves a milky film, extremely thin, but enough to need another cleaning to remove, so there's no point to using this stuff.
