How It Works

Wet & Forget Concentrate employs a unique combination of biodegradable selective fungicides that target moss, mould, lichen, algae, and general biological growth. When diluted with water and applied to a dry surface, it immediately attacks the growth. The weathering process then gently removes the decomposing growth over time, without damaging the surface.

How to Apply

  1. Preparation: Sweep off leaves, dirt, and debris for maximum penetration.
  2. Dilution: Mix one part Wet & Forget with five parts water in a garden sprayer.
  3. Application: Spray the affected area to the point of saturation. Do not hose off.
  4. Timing: Apply during overcast, dry conditions and avoid application if rain is expected within the next 12 hours.

When to Expect Results

  • Algae will disappear within days.
  • Moss will turn brown within a few days.
  • Black mould will improve within 4-6 months.
