Just to let you know, I find wet wipes/baby wipes superb for cleaning off Silicon from hands or any where where it is not wanted. The wipes can also be placed over your finger and any uneven edges can be cleaned up. They leave no residue behind and no sticky fingers.
I was told by a pal that methylated spirits softens silicone and this is useful in those instances where you want to remove it to put a fresh lot in, such as a bath seal. Not tried it myself so it would be good to hear if this is good information or not. (that is not drinking it but removing silicone) DWD
At least we know why a place in California is called Silicon Valley. 18 year old californian girls ask their parents for money for silicon implants. I doubt if they use meths to clean them though.
