Algae Stain Remover Multi-Surface Outdoor Cleaner Concentrate
This cleaner works with a simple spray-and-leave method. You dilute the concentrate with water, spray it on the affected surface, and then leave it. The product kills the organic growth, and natural elements like wind and rain gradually wash the stains away over time without scrubbing or pressure washing.
How the Product Works
The formula contains biodegradable fungicides and surfactants that attack the spores of moss, mold, mildew, and algae. These ingredients break down the growth, and the weather slowly removes the dead residue from the surface.
- Green stains may disappear in 1–2 weeks.

This cleaner is mainly for outdoor surfaces, including:
- Roof shingles

It can also be used on wood, aluminum, and sealed surfaces when applied correctly.
Key Features

- Safe for many outdoor surfaces
- Long-lasting cleaning results (often up to 1 year)
- One gallon concentrate makes multiple gallons of cleaning solution
Pros

- Works on many outdoor surfaces
- Long-lasting prevention of moss and algae
- No pressure washing required
Cons
- Not an instant cleaner (works slowly)
- Mainly designed for outdoor use only
- Heavy stains may require multiple applications
Brite & Clean® (Bright & Clean) Ultimate Hard Water Stain Remover®

It is commonly used on glass shower doors, windows, sinks, chrome fixtures, and porcelain surfaces to restore their original shine.

To use it, you sprinkle the powder on a damp cloth or towel, rub it on the stained area, and rinse after the stains disappear.
