Granite, basalt, slate, and other acid-resistant stones are built for durability. They\u2019re dense, hard, and naturally less porous than softer stones like marble or limestone. That\u2019s why you\u2019ll find them everywhere, from busy hotel lobbies and family kitchens to outdoor patios and entryways.<\/span><\/p>\n

But even strong materials need careful maintenance. While these stones can withstand acids that would etch marble in seconds, they\u2019re not invincible. Every day, residues, limescale, rust, and oil can all leave marks if they\u2019re not cleaned correctly. The good news? With the right cleaners and a little chemistry knowledge, stains on acid-resistant stone are rarely permanent.<\/span><\/p>\n

What Makes a Stone \u201cAcid-Resistant\u201d?<\/span><\/h2>\n

Not all natural stones react the same way to acids; it depends on what they\u2019re made of. Stones like granite, basalt and quartzite are rich in silicate minerals such as quartz and feldspar, which are chemically stable and don\u2019t react with mild acids. That\u2019s what makes them acid-resistant, and why products like <\/span>DETERDEK<\/b> can safely remove mineral build-ups or construction residues without etching the surface.<\/span><\/p>\n

However, \u201cacid-resistant\u201d doesn\u2019t mean \u201cacid-proof.\u201d Strong or undiluted acids can still dull the finish or damage sealers if left too long, so always test first and follow dilution guidelines. By contrast, <\/span>marble, limestone, and travertine<\/span><\/a> contain calcite, a mineral that reacts instantly with acid. Even something as mild as lemon juice can leave a mark, whereas granite would stay unaffected.<\/span><\/p>\n

Understanding this distinction helps contractors match each surface with the right product, ensuring effective cleaning without damage.<\/span><\/p>\n

From Neutral to Acidic: Matching the Cleaner to the Job<\/span><\/h2>\n

Now that we know what makes a stone acid-resistant, the next step is keeping it looking its best. The right cleaner really depends on two things: what kind of dirt or stain you\u2019re dealing with, and how the product itself is formulated.<\/span><\/p>\n

FILA\u2019s approach covers it all. The system works across the full pH range \u2014 starting with gentle, neutral cleaners for everyday care, moving to alkaline formulas for grease or organic marks, and finishing with acid-based options when you need to tackle mineral build-up.<\/span><\/p>\n

 <\/p>\n

Routine Cleaning<\/strong><\/h5>\n

Even the hardest surfaces benefit from gentle, regular care.<\/span> CLEAN<\/b>ALL<\/span><\/a> is FILA\u2019s go-to neutral cleaner for day-to-day maintenance across ceramics, porcelain, LVT, and concrete, and it\u2019s just as effective on sealed granite or slate.<\/span><\/p>\n

When diluted 1:200, it lifts everyday dust, light dirt, and footprints without leaving residue or film. On large projects, it can run through floor-cleaning machines for a streak-free finish. For tougher grime, contractors can increase the concentration to 1:30, scrub lightly, and rinse.<\/span><\/p>\n

Routine use of a neutral cleaner helps prevent buildup that can eventually require harsher products. It\u2019s the first line of defense before stains have a chance to set.<\/span><\/p>\n

Clever Solutions for Organic Stains<\/strong><\/h5>\n

Most stains that appear on granite, slate, or quartzite are organic, such as coffee rings on a countertop, greasy marks on a floor, or food spills left to sit overnight. These respond best to alkaline chemistry.<\/span><\/p>\n

PS87<\/b><\/a> is the workhorse for this category. It\u2019s a three-in-one cleaner, degreaser, and wax remover that tackles oils, grease, and other organic residues without harming the stone.<\/span><\/p>\n
