How to SCRUBB S45 Decking Cleaner
- Preparation: Sweep away loose dirt, leaves, and debris before applying. This allows the cleaner to penetrate deeper and work more effectively.
- Application: Pour or spray S45 Decking Cleaner directly onto the surface using a garden sprayer or watering can. Do not dilute.
- Cleaning Process: Use a stiff-bristled brush to scrub the solution into the decking. Let it sit for 15–30 minutes to break down ingrained grime, algae, and organic stains.
- Heavy Stains & Build-Up: For deeply embedded grime or older stains, allow up to 1 hour of contact time before rinsing.
- Rinse Thoroughly: Use a pressure washer or garden hose to rinse off the cleaner. Make sure all residue is removed. Allow decking to dry completely before applying any finishes.
