Stone patios, walkways, and garden ornaments can accumulate dirt and grime over time, detracting from the outdoor space they are in. Knowing how to clean and remove stubborn grime is essential for maintaining stone surfaces.
How To Clean Outdoor Stones
Here are some tips for cleaning outdoor stones:
- Identify the Grime: Determine the nature of the grime you’re dealing with. Is it algae, moss, oil, or something else? The type of grime will dictate the cleaning product needed.
- Use a Specialized Cleaner: For algae, use a specialized cleaner, such as RPB Algae Remover specifically designed to target algae. RPB Patio Cleaner is an excellent choice for general dirt, grime and blackspot.
- Repeat if Necessary: Stubborn stains may require a second round of cleaning. Be patient and persistent, as some stains may take time to lift completely.
Prevent Future Stains
Here are some tips to prevent future stains:
- Reduce the amount of shade by trimming back trees and bushed to reduce the moisture that contributes to algae growth
- Apply a sealant to your stone surface to create a barrier against future dirt, grime and algae.
- Periodically inspect your patio for signs of black spots, mould, mildew, or lichen and clean immediately to stop stains from setting in.
