3. Cleaning chemical

For persistent stains, such as oil stains, you will need to break down the stain with chemicals to rinse them out quickly.

Bleach is one of the most commonly used chemicals at home. Although bleach can be hazardous to the plant’s environment, using oxy bleach is better than chlorine bleach, which is harmful. This method is great for eliminating tough stains from your rock.

After around 10 minutes, it will start to froth, suggesting that the bleach is working. Rinse thoroughly with clean water.

Although bleach is highly effective, it is toxic to plants. If it happens to splash on your plant, thoroughly rinse it with plenty of water.

Other chemicals, such as muriatic acid, are not suitable for cleaning rocks since they cause them to fade.
