There's a type of gloves that requires less attention while cleaning: fabric gloves With these models, to play it safe (and not end up with a really dirty glove), it's useful to wipe a humid cloth or microfiber on the surface after each use to remove the dirt.
Once again, the gloves need to be dried in a well-ventilated place far from direct sources of light.
Let's be realistic: who does that after every ride? Ok, so let's take it to plan B!
1. Wear them as if you were going out for a ride
2. Immerse your hand in a basin filled with cold water and neutral soap
3. Gently rinse the hands
4. Leave them out to dry slowly, in a well-ventilated place far from direct sources of light
You need to pay attention to the position of the tips, which need to face downward. In particular, do not clip with clothes pegs on the fingers as it may alter the shape of the glove.
