Understanding this helps distinguish normal ageing, misuse, substrate defects and the treatment actually required.<\/p>\n<p>This guide separates four questions. Is the mark a deposit, stain or surface change? Which stone and finish are involved? Which method is compatible? How will a test demonstrate that it works without causing damage? This prevents product selection based on a single claim.<\/p>\n<p>Begin by recording the location, use, moisture, traffic, exposure and appearance. Identify the stone and finish, list products already used and note which points require testing or specialist advice before treatment.<\/p>\n<\/section>\n<section class=\"miu-subsection\">\n<h2>Worked project scenarios<\/h2>\n<p>For grease, penetration into the pores is the key issue. Identify the contaminant and stone, then test a suitable poultice and allow full drying before judging the result.<\/p>\n<p>For acid damage, loss of polish is a change to the stone surface rather than a stain. Neutral cleaning cannot restore it; controlled mechanical refinishing may be required.<\/p>\n<p>For rust, investigate metal migration and the moisture source before using a specialist remover. Some products can alter the stone, so a test is essential.<\/p>\n<p>For cement or grout haze, conventional acid cleaners can etch calcite-based stone. Identify both the residue and stone and select a compatible method.<\/p>\n<\/section>\n<section class=\"miu-subsection\">\n<h2>A structured decision method<\/h2>\n<p>The method below turns cleaning questions into decisions that can be checked.
