Brilliant use of the word 'obviously' there. Also, the Sun obviously goes around the Earth, which is obviously flat.... I have found that it does something kinda weird to PVC, and makes it go milk and slimy, obviously it is breaking down the plastic ...
The 'slime' you refer to is more likely to be the saponification of the oils on your hands. I also get the 'milky' look with various bits of plastic if I leave them in percarb too long. I usually try to avoid this if it's unnecessary.
