That is just so strange. Volkan is indeed demonstrating that he is
a crafty fellow! Brake fluid, what the heck! For a wetting agent,
that would have been the last thing I would have tried.
As another possiblity for a wetting agent, if someone out there is
trying this and wears contact lenses, I believe one of the chemicals
used to clean or rinse them is a wetting agent. It's been nearly 40
years since I tried wearing contacts and for some reason I
remembered this information about them.
Brake fluid - I am going to be pondering that one for a while!
