|---|---|---|---|
| Brown or dark staining persists | Deep staining from mineral deposits or organic matter | Apply moss/algae remover; re-clean with rotating brush and rinse thoroughly | Regular light cleanings to prevent buildup |

Tips For Best Results
- Test cleaners on a small, inconspicuous area before full application.
- Work in the shade to slow drying and improve cleaning effectiveness.
- Use a back-and-forth, overlapping brushing pattern to avoid streaks.
- Rotate tool heads to prevent uneven wear when using a rotating brush.
