I'm not surprised petrol did this... the amount of nasty chemicals in it, at least one of them is bound to do something bad. Probably the toluene or benzene in it. Neither of these is particularly good for you.
On a related note, how many of you wear gloves when handling automotive products such as grease etc? Not many I'd imagine. Neither do I but you really should - things like wheel bearing grease are often lithium-based and repeated or prolonged skin contact to them isn't recommended.
