Never use these on PU or faux leather
Nail varnish remover or acetone. Strong solvents such as acetone and ketones cause immediate damage to artificial leather. [3] Songmont says acetone will melt a vegan leather bag's surface and wipe out the grain. [7]
Magic sponges (melamine erasers), scourers or stiff brushes. They can sand off the thin PU coating and leave a dull, scuffed patch. [3][7] Avoid abrasive cleaners. [1][5]
Bleach and strong household cleaners. Don't use bleach unless the maker says you can. [5][6] Harsh cleaners, like the ones used on tiles and toilets, can strip the protective top coat, which then lets dye sink in more easily. [2]
Heat. No hairdryer or radiator to dry it: heat can damage, warp or melt faux leather. [7][8]
Soaking it, or a bag in the washing machine. Songmont says a vegan leather bag should never be machine-washed or submerged. [7]
