The answer to tough stains on the floor is to first identify the type of stain and then use the appropriate cleaning method. Common causes of tough stains include spills, tracked-in dirt, and built-up grime. Symptoms may include discoloration, stickiness, or a lingering odor.
For DIY solutions, start by trying a mild detergent or floor cleaner. Scrub the area with a stiff-bristle brush or mop, and let the cleaner sit for a few minutes before rinsing. For tougher stains, you may need to use a stronger cleaning solution like a diluted bleach or vinegar mixture. Always test the solution in an inconspicuous area first. If the stain persists, it's best to call in a professional cleaning service to deep clean the floor and restore its appearance.
