Dave,
Yes, it was interesting. I was actually a molecular evolutionary biologist, using DNA, RNA and other biological polymers to look at evolutionary history and the processes that influence molecular evolution.
I realize silicas and silicone are different, which is why my thinking wasn't too bright
.
I am assuming that DOT 5 contains polysiloxanes, yes? Maybe in the form of -SiO-R where R is some sort of organic group like an acetate? I am also assuming that the R is hydrophobic? If so, a strong amphiphillic detergent might also work and be safer than stuff like xylene. We used to wash silane off of glass plates using Alconox. Silane is obviously different, but similar in being a silicon compound that is very slippery and water insoluble.
Just exploring ways to reduce the use of nasty organic solvents.
