Chemical reactions in gear, discolored silicone, rubber, decomposition

[Luango]

I need a reminder of what things should not touch and what products should and should not be used for knives, zippers, masks, etc. Silicone gear should be kept away for neoprene but what else?

Sun screen: what does it do to neoprene?
Paraffin: for zippers good or bad? synthetic products or candle wax?
Silicone grease/spray: use it on everything?
Plastic: does anything hurt it?
WD-40: Never use petroleum
Teflon, Graphite: they're not silicone so...
Alcohol: rubbin' or drinkin'
mildly acidic solution:

Well the silicone in your mask will discolor if it is stored touching neoprene.

I can attest to this, I have a spare mask with a brown skirt from resting against a wetsuit in storage. Looks terrible, but still perfectly functional.
