Universal scourers impregnated with a cleaner, made of stainless steel wool.
They are used to clean fat from pots, pans, ceramic plates, ovens, sinks and fireplaces.
Reusable cleaner - until the cleaning agent runs out.
 They don't scratch the surface!
Lightly wet the cleaner so that the cleaning agent activates, clean the soiled item and then lightly rinse the cleaner with water so as not to rinse the cleaning agent and let it dry.
