How to Remove Algae From Outdoor Carpet

How to Remove Algae From Outdoor Carpet

Outdoor carpet is a quality addition to an outside patio or cement porch. A once bare surface is radically transformed into an elegant and appealing one. Carpet is significantly impacted by weather. Many people purchase carpet thinking it doesn't need continual maintenance. I let my patio rug go way longer without using GP66 than I should have. The picture below is a full year of carpet baking in the sun. Depending on the severity of the weather, the appearance will diminish quickly. The biggest culprit, algae formation! Wet and humid conditions can cause algae to spread fast in an outdoor carpet. The disgusting green slime can deteriorate an outdoor rug if not taken care of. 


Step 1: Sweep up any debris or dirt on the rug or carpet 

Step 2: Spray GP66 full strength on the mossy green area, really saturating the entire surface

Step 3: Be patient; let it sit for about 10 minutes. 

Step 4: Use a home pressure washer or a stiff scrub brush.  A long-handled scrub brush is preferable to avoid bending over.

Step 5: Rinse with a garden hose. 

Step 6: Let it dry in the sun and come back to it tomorrow. 

The picture below is a real before and after image of my carpet patio with no manipulation. 

Check it out! Give GP66 a Try! We would love to hear from you how this went :)
