Wire Brushes and Pumice Stones
These tools work by physically abrading the scale off the tile — but they abrade the tile glaze right along with it, leaving fine scratches that create more surface texture for the next round of scale to grip even faster.
Full-Strength Muriatic Acid Applied Without Control
Muriatic acid dissolves calcium, which is why it's part of the professional process — but consumer application without proper dilution and dwell-time control commonly etches grout lines and discolors certain tile glazes.
What Professional Descaling Does Differently
Blues Home Services uses pH-balanced descaling formulated for the specific tile material, applied with controlled dwell time and non-abrasive tooling, followed by full neutralization and rinse — removing scale with zero scratching or etching.
