Application Instructions
DIRECTIONS FOR USE:
Mixing Guidelines: Dilute the concentrate with water at a ratio of 1:10 to 1:20, depending on the level of soiling.
- Apply the diluted solution evenly across the surface using a watering can or garden sprayer.
- Scrub thoroughly with the Osmo Decking Scrub Brush or a stiff-bristled broom to loosen dirt and grime.
- Rinse the surface with clean water to remove all cleaner residue.
- Allow to air dry — drying time is approximately 1 hour under normal conditions.
For larger areas or heavier soiling, we recommend using the Osmo Decking and Flooring Cleaning Machine.
Important: Always test product compatibility on a small, inconspicuous area before full application.
