Aggregate flooring (that is, a rough and rocky concrete floor without a smooth top layer) can be notoriously difficult to clean. While sweeping and mopping may be good enough for some jobs, really dirty floors might require chemical compounds or muriatic acid. To keep your aggregate flooring sparkling clean, follow the following steps.

Step 1 – Sweep the Floor

Remove loose dirt by vigorously sweeping your aggregate flooring with a large, stiff-bristle broom. Scrape off any gum or sticky residues. Follow this by sweeping with a microfiber mop to pick up any leftover dirt particles.

Step 2 – Mop the Floor

For grimy aggregate flooring, mix warm water in a bucket with household cleaner. Vigorously mop the floor with this solution. If the dirt continues to cling, try mopping with a solution of warm water and a chemical cleaner from the hardware store.

Step 3 - Hydrochloric Acid

The dirtiest, most resistant aggregate floors might require hydrochloric acid (also known as muriatic acid). This is a dangerous compound that should only be used if you’ve had previous experience with industrial chemicals. Wear protective gloves and goggles at all times and don’t allow the acid to come in contact with your skin. Mix 1 part acid to 20 parts water and apply to the floor with a sprayer. Rinse thoroughly, preferably with a power washer.
