Homeowners struggling with grimy patios have found a surprising solution: cat litter. According to Andy McLaughlin of RF Paving, scattering cat litter over tough oil and grease stains can effectively lift them without damaging the paving.
How to Use Cat Litter on Patio Stains
McLaughlin recommends sprinkling cat litter over the stain, grinding it in, and leaving it overnight. However, he warns to sweep it away before rain, as moisture turns it into a thicker, mud-like substance that is harder to remove. With dry and warm weather forecast, the coming days are ideal for this method.
Caution with Vinegar and Other Cleaners
While white vinegar is a common cleaning choice, McLaughlin cautions against using it carelessly on patios, especially natural stone. The acid can break down stone surfaces and protective sealants, causing etching, dull spots, and even rusting. For example, vinegar can react with iron in limestone paving, leading to stubborn rust stains.
Instead, he suggests using a pH-neutral outdoor cleaner or a light soap mixed with water. These methods reduce harsh chemicals and high-acidity products, keeping the paving and joints in good condition.
One product to avoid entirely is indoor surface cleaners, as they can cause significant, sometimes permanent, damage to paving.
