Our decontamination gel contains disodium EDTA, sodium bicarbonate, lauryl ether 7. It can be highly permeable, allowing the solution to penetrate deeply and quickly break down potentially stubborn stains. Its application method is simple: apply the gel evenly to the stained area and let it sit for two hours to dissolve the stain. Then wipe off the residue with a damp rag. It solves stubborn surface stains from the root, ensuring effective cleaning without leaving any residue and stains, providing you with long-term cleaning space!
