What are the effects of acid-based cleaners on concrete bench coatings?

Acid-based cleaners are often used for their powerful cleaning properties, but their effects on concrete bench coatings can be significant. These cleaners, typically containing hydrochloric or phosphoric acid, can degrade protective coatings, leading to discoloration, etching, or even structural weakening over time. While they effectively remove stains and grime, prolonged or improper use may strip the coating entirely, exposing the porous concrete beneath to further damage. To minimize harm, dilute acid solutions, limit exposure time, and rinse thoroughly with water. For coated concrete benches, consider pH-neutral alternatives or specialized concrete cleaners to preserve the coating's integrity and longevity. Regular maintenance and proper cleaning techniques can help extend the life of concrete bench coatings while keeping them looking their best.
