My tredstep showjumper pro gloves are starting to look a bit grubby and stinky. How do you clean your gloves? Mine are partly lamb skin so I can't destroy that but I think the rest of it is just synthetic material.
Bowl of water a few drops of woolite or similar wear the gloves wash by gently rubbing your hands together , rinse a few times in warm water the last time with a few drops of fabric softener ( the lanolin in it will help condition the leather ) dry pat with towel to remove most of water then ease off hands and dry flat in warm place away from direct heat source put on gently when almost dry to reshape , that's how I treat gloves that I love.
