The best way to clean products such as rugs, is to hang them outside in fresh air.
If you stain it, clean it as quickly as possible. Water can remove stains that did not have a chance to seep into the fibers. If you use water, let it dry in the sun before using it again. If it’s still wet there is a chance it will mold. It is very important to never get it soaking wet! It is an absorbent fiber and so it will absorb all the water which can cause stains.
These are all  natural fiberd so do not use harsh chemicals on stains.
