Application Instructions

General Cleaning

1. Dilute Solution
   Mix 1 part detergent with up to 20 parts water in your pressure washer’s detergent tank or external soap injector.

2. Apply Detergent
   Apply evenly using a low-pressure setting.

3. Dwell Time
   Allow solution to dwell for 5–10 minutes to penetrate dirt, mold, and mildew.
   Do not allow detergent to dry on the surface.

4. Rinse Thoroughly
   Rinse using a white (40°) or green (25°) nozzle at low to moderate pressure.

Spot Treatment

• Apply detergent full-strength to heavily stained areas using a pump sprayer

• Lightly agitate with a soft brush if needed

• Rinse thoroughly with clean water

Application Tips (Best Practices)

Nozzle Selection

• Use 40° (white) or 25° (green) nozzles

• Avoid 0° (red) and 15° (yellow) nozzles — excessive pressure can damage wood

Maintain Proper Distance

• Keep spray wand 18–24 inches from surface

• Use long, even strokes

Avoid Direct Sunlight

• Clean during cooler parts of the day or in shaded areas

• Sunlight can shorten dwell time and cause uneven results

Rinse Before Drying

• Always rinse detergent before it dries to prevent residue

Common Mistakes to Avoid

• Using excessive pressure that gouges or splinters wood

• Allowing detergent to dry on the surface

• Cleaning in direct sunlight

• Using harsh bleach or non-wood-safe chemicals

• Skipping a test spot on older or weathered wood

Deck & Fence Cleaning Frequency

• Recommended 2 times per year (spring and fall)
