A sponge is a handy tool for washing and rinsing large surfaces. It is also suitable for applying wax. A sponge made of cellulose absorbs the dirt and does not push it ahead.
* before the first use, the cellulose sponge is thoroughly rinsed
* the sponge is rinsed and air-dried after each use
* occasionally it is good to disinfect the sponge with e.g. detergent containing chlorite
