How should Dumaplast panels be cleaned and cared for?

Use ordinary household products for looking after them. The panels can be polished to their original condition using a soft, non-abrasive cleaning agent. Normally you only need a damp cloth to clean the panels thoroughly. Do not use abrasive, aggressive substances or cleaning products based on chloride. We do not recommend using solvents.

For removing any limescale residue, we recommend the following products for Dumawall+ and Dumawall XL:

Antikal Classic

HG scale remover
