Porcelain is dense and stain-resistant, but the surrounding grout, polished finish and adjacent hardware can change what is safe. The visible tile may tolerate a method that the installation around it does not.
White rings and cloudy spots on porcelain tile are usually surface deposits or cleaner film, but polished finish changes and grout can mimic hard-water stains. Diagnose the mark before descaling.
