Our cleaning and decontamination gel is carefully formulated with carbomer and triethanolamine. Designed specifically for quickly dissolving stubborn stains and black spots to enhance cleaning efficiency. The usage method is extremely convenient: Install the tip cap, evenly apply the product to the stained area, let it stay for two hours to dissolve the stain, and finally wipe off the residue with a damp cloth. And it can help remove odors and keep the seals and crevices fresh for a long time.
