Surface compatibility matters most: acidic cleaners can damage some natural stones and metal fixtures, while non-acidic or acid-free formulas offer safer options for sensitive surfaces like marble or porous grout. Consider the stain type—rust, mineral buildup, soap scum, or haze—and choose a product formulated to address that issue. For grout lines, stronger formulas may require scrubbing or agitation, while no-scrub options reduce wear on grout. Dilution instructions affect both cost and effectiveness, so follow label directions for optimal results. Always test in an inconspicuous area before full application.
