Hand washing is the best way to maintain acrylic products as dishwasher rinse agents and heat can cause cracking and crazing over time.
Do not use a rough sponge or abrasive cleaning brush on acrylic.
Straight high-proof alcohol is not recommended for acrylic material, as it can cause damage if left in glass over a long period of time.
To safely remove sticker residue, please use oil based lubricant such as WD-40 (or any other oil-based brand), or vegetable oil such as Wesson.
DO NOT use GOO-Gone, nail polish remover or turpentine, as these will damage acrylic.
