How To Safely And Effectively Remove Algae From Outdoor Fabric

Due to its strength and resilience to the elements, outdoor fabric is a preferred material for patio furniture, awnings, and other outdoor furnishings. Nevertheless, algae development can discolor and deteriorate the outdoor fabric, making it vulnerable to this problem. 

Many elements, including moisture, humidity, and a lack of ventilation, can contribute to the formation of algae. 

Algae development can permanently harm the fabric if not handled. In this post, we’ll go over several efficient ways to remove algae from outdoor fabric and stop algae development in the future.

How To Remove Algae From Outdoor Fabric

Algae may be expected in outdoor materials like cushions, umbrellas, and awnings. If ignored, it may become unattractive and harm the fabric. Thankfully, cleaning algae from outdoor fabric may be done in several ways. This article will review some of the best strategies for getting algae off the outdoor fabric.

Brush off Loose Algae

The first step in removing algae from outdoor fabric is to brush off any loose algae using a soft-bristled brush or a broom. This will help to remove any excess algae and prepare the fabric for cleaning.

Use a Bleach Solution

Algae from outdoor cloth may be eliminated with a bleach solution. Combine one cup of bleach and one gallon of warm water in a bucket. Scrub the impacted cloth portions by dipping a soft-bristled brush into the solution. While using bleach, be sure to use rubber gloves and safety goggles.

Use Vinegar Solution

A vinegar solution can also be effective in removing algae from outdoor fabric. Combine white vinegar and warm water in a spray bottle in equal parts. Spray the remedy over the fabric’s trouble spots, then wait 10 to 15 minutes before using. After that, clean the algae off the cloth with a gentle brush. To remove any vinegar or algae that may still be on the cloth, thoroughly rinse it with water.

Use a Pressure Washer

A pressure washer can remove the algae from outdoor fabric if they are particularly stubborn. For best results, use a low-pressure setting to protect the cloth. Move the pressure washer nozzle back and forth over the impacted regions while keeping it about 12 inches away from the cloth. Use a pressure washer with caution while wearing safety gear and glasses.

Employ An Industrial Algae Remover

A commercial algae remover can be used if the abovementioned techniques fail to eliminate algae from outdoor cloth effectively. Choose a product specially made for outdoor fabric, and follow the manufacturer’s directions thoroughly.
