Natural marble is extraordinarily durable — it has been used in buildings, sculptures, and functional objects for thousands of years. But it has specific vulnerabilities that are easy to accidentally trigger if you do not know what they are. Here are the seven most common marble mistakes, and exactly why each one causes damage.

1. Never Use Acidic Cleaners

This is the most common and most damaging mistake. Vinegar, lemon juice, citrus-based sprays, bathroom tile cleaners, and most 'natural' multi-surface cleaners are acidic. When an acid contacts marble, it reacts chemically with the calcium carbonate in the stone and creates a dull, rough patch called an etch mark. Etch marks are not stains — they are actual surface damage and cannot be wiped away. They require professional polishing to correct. Stick to pH-neutral cleaners only, or plain warm water.

2. Never Put Marble in the Dishwasher

The combination of heat, alkaline detergent, and water pressure inside a dishwasher will damage marble on a single cycle. The heat causes thermal stress. The detergent strips the surface. The water pressure forces moisture into the stone's pores. Your marble mortar, coasters, or wine cooler will come out looking dull, with a compromised surface that is more susceptible to staining from that point forward.

3. Never Leave Marble Wet

Marble is porous. Leaving it wet or in standing water allows moisture to penetrate the stone, which over time causes two problems: first, dark water marks and potential mould in the pores; second, repeated wetting and drying cycles can cause microscopic internal stress fractures. Always dry marble completely — immediately — after any contact with water.

4. Never Place Hot Objects Directly on Marble

A hot pan from the stove, a heated curling iron, or a candle that has been burning for hours can all cause thermal shock when placed directly on marble — particularly on thinner pieces like coasters and trays. Always use a trivet, cloth, or pad as a barrier. This is especially important with onyx, which is more thermally sensitive than standard marble.

5. Never Use Abrasive Scrubbers

Steel wool, scouring pads, rough cleaning brushes, and even coarse paper towels will scratch the polished surface of marble. Once scratch marks are in the surface, they catch light and become visible — and require professional polishing to remove. Always use soft microfibre cloths or soft silicone brushes for cleaning marble.

6. Never Ignore Spills Immediately

Red wine, coffee, tomato, cooking oil, beetroot, turmeric — anything with strong pigmentation or acidity should be blotted (not wiped — wiping spreads the spill) from marble immediately. The longer a pigmented or acidic liquid sits on marble, the deeper it penetrates. A spill cleaned within 30 seconds leaves no trace. A spill left for an hour may leave a permanent stain.

7. Never Assume All Marble Is the Same

Green onyx, honey onyx, white marble, black marble, and red marble all have slightly different densities, porosities, and sensitivities. Onyx in particular is more delicate than standard marble — it is more porous and more thermally sensitive. Our full Marble Care Guide covers the specific care requirements for each stone type.

The Simple Rule That Covers Everything

When in doubt: soft cloth, warm water, dry immediately. Almost every marble care mistake is a variation on using something too harsh or leaving moisture on the stone too long. Keep it simple and your Artreestry pieces will look exceptional for decades.
