Never throw your beloved ones in the washing machine, they will lose colour and shape.
Eraser, toothbrush, clean cloth, liquid soap and sneaker wipes or occasional baby wipes.
The eraser helps you get rid of discolourations. Brush off excess dirt with the toothbrush before adding any water. Next step is clean cloth with a little liquid soap or detergent, then water and toothbrush again. Rub away stains carefully. Sneaker- or baby wipes are excellent tools as well, but don’t use the baby wipes too often, they dry out the leather.
Always read the care label thoroughly before treating any stains. Make sure that the treatment won’t damage the fabric, by testing a small amount somewhere less visible.
