The "Wall Stains Cleaner Not For Distemper Paint" in the 500ML size is a high-efficacy, specialized cleaning formula designed for larger cleaning tasks and regular maintenance on walls finished with durable paints like emulsion, acrylic, or enamel finishes. The formulation features powerful, fast-acting agents intended to aggressively lift and remove a wide range of stubborn stains, including grease, oil, fingerprints, scuff marks, and everyday grime, without damaging the robust polymers found in modern paint types. The critical warning—"Not For Distemper Paint"—is due to distemper's composition of chalk, lime, and water, which is porous and non-washable; the cleaner's strong components would cause the distemper paint to chalk, flake, or dissolve completely. This larger 500ML bottle offers double the quantity of the smaller version, making it ideal for cleaning high-traffic areas or multiple rooms where stain removal and surface preservation on washable paints are required.
