The presence of mold on a tent signals high humidity and improper cleaning routines. Canvas tents are known for their breathability but they can also absorb more moisture than nylon tents.
Mildew on tents and mold on tents can be removed by using specialized cleaners or homemade cleaners. Scrubbing it off is the first step to completely removing it from the canvas while soaking might be necessary for a canvas that’s deeply affected by mold or by canvas that remains stained after cleaning mold or mildew off.
What is mold?
Mold is a type of fungus that is present in the air, specifically in areas with high humidity. It spreads quicker in shaded locations that aren’t exposed to sunlight as they tend to maintain higher humidity levels for longer.
Mold feeds on organic matter and it doesn’t need sunlight to grow. It uses organic materials to grow and it eventually spreads out the more it finds these favorable conditions such as organic materials and high humidity.

Most canvas tents have UV and waterproofing coating. However, this coating wears off or it might be insufficient when there’s high humidity, dirt, and grime to serve as organic matter for mold formation.

What are the steps in cleaning mold and mildew?
1. Pitch the tent and inspect mold and mildew
A tent is easy to clean when pitched. Make sure to pitch the tent first to allow through scrubbing and to efficiently assess if mold has been completely removed from the canvas.
2. Spray the affected areas with a mold cleaner
The second step is to spray the mold on the tent and let it soak before scrubbing. Spraying is recommended for mild mold and mildew while overnight soaking is the better alternative for heavy mold formation.
3. Scrub it out with a soft brush
You can then proceed to scrub out the mold with a soft brush. Circular motions are recommended. Rinsing with clear cold water is recommended after scrubbing the mold off.
4. Let the tent air-dry
Canvas takes a long time to dry. It needs to be properly dried before the tent is packed down. A clean tent that isn’t properly dried is going to favor new mold formation on the canvas.
When to soak a canvas tent?
Soaking a canvas tent is recommended as a method to clear considerable mold expansion. Any mold that’s expanded on a full tent wall requires soaking as scrubbing can take a long time.
- When mold doesn’t come off by scrubbing
Mold might not come off by scrubbing, even when scrubbing for a long time. It’s best to have realistic expectations of the final results, to begin with. Alternatively, you can take the tent off and soak it in water (with a mold remover solution) overnight to clear all the mold off properly.
- When mildew formation has extended more than a few inches
Extensive mildew formation might take hours to scrub off without prior soaking. It’s recommended to soak each part of the tent for at least 4 hours before scrubbing it off when extensive mildew has formed on it. This process is repeated multiple times for each affected area of the canvas.
Scrubbing and soaking canvas might only come with limited results if mold and mildew have been growing for a long time. It’s recommended to deep clean a canvas tent after every extended stay out in nature.
Keeping mold away is easier than cleaning it off. This is why it’s recommended to ventilate the tent frequently and to pitch it in direct sunlight to stay away from high humidity locations.
