Can I use Universal Cleaner on marble or stone?Updated 9 days ago

TL;DR: Many customers use Universal Cleaner on marble, granite, and other stone surfaces with good results. Because stone finishes vary, polished, honed, sealed, and unsealed all behave differently. A spot test before full use is always recommended.

Stone finishes and what to watch for

Not all stone is the same, and the finish on your surface plays a big role in how it responds to any cleaning product.

• Polished marble and granite have a sealed, glossy surface. These generally respond well, but are sensitive to anything that might affect the sheen. Always spot test and buff dry promptly.
• Honed marble and stone have a matte, more porous finish. Liquids can be absorbed more readily, so avoid leaving any moisture to pool on the surface.
• Travertine and limestone are softer and more reactive stone types. Take extra care and check the results of your spot test closely before proceeding.
• Engineered stone (such as Caesarstone or Silestone) is generally more resilient, though sealant types still vary by manufacturer.
• Unsealed natural stone of any kind carries more risk. Consult your surface supplier's care guide before use.

How to clean stone safely

1. Spot test first. Spray a small amount in an inconspicuous area, wait a few minutes, wipe clean, and check for any change in colour, sheen, or texture.
2. Spray and wipe. Once satisfied with the spot test, clean the surface using light, even pressure.
3. Buff dry immediately. Do not allow liquid to pool or sit on stone. Buff dry with an Ultra Pro Cloth for a streak-free finish.

Why spot testing matters

Sealants, resins, and stone finishes vary significantly by manufacturer and age. A quick spot test ensures Universal Cleaner will not react with your particular surface treatment before you clean the whole area.

Still unsure?

Check your surface supplier's care guide, or contact the installer or manufacturer of your stone for specific cleaning recommendations.
