Cleaning Mold Outside

For large areas, a pressure washer, or garden sprayer is the easiest application method.

Agitate areas of heavy build up and allow the recommended dwell time.

Vinyl and aluminum have a tendency to stain more than wood. Strong agitation and a rinse with a pressure washer or high pressure hose will help with tough stains.

Concrete and Masonry

Concrete and masonry are very porous which allows mold and mildew spores to penetrate deeper into the surface. For best results, after applying Moldzyme® scrub the surface to work the enzymes further into the surface and rinse with a pressure washer or high pressure hose.

Re-application may be beneficial in areas of heavy growth.

Deck and Patio

1. Horizontal surfaces are problem areas for mold and mildew. The easiest application method for these areas is a garden sprayer (chemical sprayer), or for small areas a Moldzyme® Spray Bottle.

2. Apply Moldzyme® liberally and agitate with a scrub brush or deck broom. Agitation will help Moldzyme® to penetrate through the built up layers of grime to get to the problem area on the surface. Allow the recommended dwell time and rinse with a hose or pressure washer.

Siding, Brick, Vinyl, Stucco, and other home exteriors: Moldzyme® is safe for your plants, landscaping, and ground water. A tank sprayer is often easier for applying Moldzyme® to a large area. Spray Ready-to-Use over moldy areas and let sit at least 10 minutes. Brush in and rinse off with cool water. If your mortar or wood siding is older or extremely porous, brushing Moldzyme® in a second time may be more effective.
