The answer to 'pressure washing stain removal' is that pressure washing can be an effective way to remove stubborn stains and dirt from outdoor surfaces, but it requires careful technique to avoid damage. Common causes of stains include mold, mildew, rust, and oil/grease buildup. Symptoms include discoloration, fading, and a generally dingy appearance.
For DIY pressure washing, start with a lower pressure setting (around 1,000 PSI) and test on a small, inconspicuous area first. Use the appropriate detergent or cleaning solution for the type of stain, and work in sections to avoid letting the cleaner dry. Rinse thoroughly to remove all residue. For tougher stains or delicate surfaces, it's best to call in a professional pressure washing service to ensure the job is done safely and effectively.
