Avoid cleaning with harsh or scratchy cleansers. Use mild soap, soft towel, cold water.
Avoid very hot water, do not place them in a dishwasher.
Extra care is needed with alumilite and lava acrylics, they tend to scratch easier and are more sensitive to heat and pressure. Alumilites with inclusions (ribbons, glitter, chunks and pieces of stuff) may be more susceptible to breakage, handle with care.
Use soft towels to dry and clean.
