| Re: Diamond Chip Cleaner's Main Ingredient...TSP ok well apparently it's illegal to sell TSP in New York State. There is a "TSP-substitute" available, which is in liquid form, but I'm not going to mess with that.
Looks like I will be sticking with pipeshield, or maybe I'll look for TSP next time I am across the border in Ontario.
I will try to post pics of a few EP ASM $5s I cleaned in pipeshield. I don't know what the actual color is supposed to be when clean, but the ps definitely faded some of the chips-- a few are less pink on one side than the other, probably due to the fact that I flipped them over half-way through a 24-hr soak. Mineral oil darkened the color, but didn't remove the color difference. I know another CTer mentioned problems with fading in purple paulsons.
From what little I know about pigments, some colors (esp. scarlets and non-toxic bright reds) are made by precipitating organic dyes onto aluminum dust. It's possible the pipeshield eats up the dyes, just like it eats up other organic material. I think most other pigments are made of ground up minerals, like iron oxide. They're inorganic and wouldn't be affected by pipeshield. Just my thoughts on this.
Thanks again for everyone's tips. |
