- Dampen the surface with water. Use a garden hose.
- Apply some undiluted RMC Exterior Wood Cleaner.
- Scrub the treated area with a nylon scrubbing brush in the lengthwise direction of the wood until it is clean. This will cause the product to foam. For stubborn stains, repeat the treatment.
- Rinse thoroughly until all the foam has disappeared.
- Allow the surface to dry well (± 30 minutes at a temperature of 20°C and proper ventilation).
- Treat with the Rubio Monocoat exterior wood protection product of your choice.
