Chuck,

What you need is what people call a "black light", i.e. a standard dark purple UV bulb as sold in fancy dress shops and some hardware stores. It doesn't have to be anything fancy - the filament and energy saving types both work perfectly OK.

If you check the pictures of the C64 experiments Tonyyeb and I did in the gallery on the Wiki, you will see that we used energy saving bulbs.

If you search UV bulb on Ebay you will see what I mean, don't go spending a bundle on the bulb.

OK dwightdi what say you now?
Many of us non-sceintific commoners would like to know. Bleaching or otherwise it seems to have generated only reported excellent results.
In your opinion as an Airstream owner is there some negative to the "ductile" degradation?
What is the result of ductile degradation? Crumbling ? Brittleness? Fragility? or what?

thanks

Yes, this inquiring mind wants to know too. I don't want to do anything that will make the ABS more brittle than it already is from age, exposure, etc. Will using an oxy type cleaner lighten it and or make it brittle in any way?

Thanks, Mary

In simple English, no it won't affect the ABS plastic at all; all Retr0bright does it treat the fire retardant, it leaves the plastic polymer alone, unless you overdo it by making the H2O2 strength too strong. About 10% H2O2 strength is just enough to treat the fire retardant without attacking the plastic polymer.

Check the website Retrobright originally posted. This was a formula they developed to treat old computer cases to make them look pretty again. Computer cases are required by the US and European governments to be fire resistant. The grade of ABS used is a special fire retardant grade. The ABS manufacturers add a bromide compound to make it fire retardant. Old compouter cases turn yellow because they are usually used in offices that are lit with Florescent lights which give off large amounts of UV light in addition to the visable light.

Your Airstream components that are made from an ABS are made from a grade which does not contain a bromide. The government does not require trailers to be flame retardent. Retrobrite contains oxygen bleach just like Chlorox 2 or Oxichean. It will attack and oxidize the yellow color bodies that are formed when plain ABS is exposed to sunlight for a long time. It would also attack any smoke residuals that might have been absorbed into the plastic. I am not sure if it is strong enough to oxidize any of the other polymers in the ABS formula or whether it will reduce the already degraded ABS and further reduce its elongation or impact resistance.

So Dwight.....

I'm confused. Are you saying it's safe to try or that it might weaken the ABS somehow? We simple folk need a yeah or nay .

Thanks, Mary

Smile A Safe Polish for ABS Plastic

I'm wondering if Rivet Master or Extreme Alchemist have a suggestion for how to clean and polish my ABS clarinet that I take for companionship on trips. It's old and black and now going thru cleaning, but what's the best kind of polish or wax to use on it so it stays nice looking longer while fighting off fingerprints, those of my grandkids, etc. I don't want to use something that will make the ABS fall apart in my hands as I'm playing.

I would recommend Armor All for your clarinet. It will provide the fingerprint and UV protection you need.

OK..."enjoyed" the chemistry lesson, but still have a stupid question. My bathroom fixtures in the 67 are light blue/green. Will either of these products restore them to the origional color or am I looking at sanding?

LOL,

Yes, your blue-green fittings will be just fine. Retr0bright will restore the color with no problems.
