For the first time in my life o tiled the kitchen floor and didn't use any cloves after about 4 hours using cement it hardened on to my hands I was it off and my nails where yellow and some of the skin on my hands despaired and was bleeding
Maybe try washing them with lots and lots of lemons... it bleaches them back to its natural colour, although I would maybe go to the doctors if they were bleeding!
Whoops, sorry, DON'T wash them with lemons if they're bleeding as the acid may make them worse! I would probably go to the doctors but would put some serious moisturiser on them first!
The lemon only really helps with nicotine, when I smoked it worked. Also, I soak my white underwear in a bucket of hot water and loads of chopped lemons if the colour is looking a bit tired. Sorry I wasn't much help! X
