Removing Paint From ABS Plastic...

the good thing about caustic is if you get it on you just wash it off with water. If it's only a little bit than a couple minutes should do if your really concerned about the amount on your skin keep under running water for a good 20 mins. It's not really a burn more of an itch

Caustic Soda is Sodium Hydroxide (NaOH). look for this as an active ingredient in domestic "draino" type products. It could be as strong as 90% so be careful with it. Don't breath the dust if you get powder type and keep it off your skin and eyes. Even light dust that floats in the air and lands on your skin will cause irritation if its up near 90%.
Mix it with water at about 1 cup to 20 lts water and soak a sample over night to see if it is strong enough. Keep it away from aluminium, it will eat into it and give off flammable gas. Have a read up about it first so you know what you are dealing with.

Potassium Hydroxide will do the same.

Yeah, thanks for the info mate.. I got a can of Easy Off Heavy Duty Oven cleaner (it had the highest amount of Sodium Hydroxide, I think 54grams per kilo which works out to about 5%..) It works pretty well.. I just sprayed it on with a heavy coat and left it to sit until it almost dried, then got a toothbrush ans the paint just wiped of with a cloth..

There is a small amount of black paint left, so I am going to give it another coat and try to get rid of it..

Yeah, I got a little bit on my hand and washed it off straight away.. But your right, it is more of an itch than a burn..
