The answer to tough stains on move-out cleaning is to identify the stain type and use the appropriate cleaning method. Common causes of tough stains include food spills, grease, ink, and ground-in dirt. Symptoms include discoloration, lingering odors, and stains that won't come out with basic cleaning.
For DIY solutions, start by testing a small, inconspicuous area with a mild cleaner or stain remover. Avoid using harsh chemicals that could damage surfaces. For tougher stains, use a combination of elbow grease, stain-fighting products, and a little patience. If the stain persists, it's best to call in a professional cleaning service that has the right tools and expertise to tackle the job.
