Someone mentioned a solution used to clean off Organic contaminants called RCA Etch or something similar. It was developed in the 70's or earlier, but I can't find any literature on it. I believe that it contains H2O2 and H2SO4 but I don't know in what proportions. If anyone can help me out, I'd appreciate it. We're having some problems with "sticking" of our capacitive accelerometers and want to eliminate the possibility of organic contaminants. Any suggestions would be appreciated. Thanks.
