Hi Depends on what paint you used. I usually use Model Master Enamel and if it's good and cured then use some Windex on a cloth very sparingly. They also sell something called Goo-Gone that works quite well. Also you might try using Turtle Wax Liquid Automotive Wax but be very careful with it as it will remove some of the paint sometimes. Hope this helps.
