Use only water to clean your custom painted shoes
How do i clean custom painted shoes without removing the paint in it.
after you finished, a towel, paper towel, and soft bristle toothbrush would do just fine but ususally dont recommend toothbrush becasue it can remove the paint.. but if carefully done you can remove the dirty of the edges of the painted images
If you didn't seal the paint you need something super soft that won't scuff the paint. So never use a toothbrush is out them or anything that contains methyl spirit..
Water us the best. Maybe abit of warm water will do thr cleaning between the sides of the images painted..
