How to Stop the Mold on Your Canvas Patio Furniture

Canvas patio furniture is a great addition to any outdoor living space. They are functional and cheap, but there is one major problem that you may encounter: mold!

The sun and the humidity in the air can do wonders for your canvas patio furniture by making it look old and worn out too quickly.

We have compiled some tips on how to stop the mold from ruining your pieces of canvas patio furniture so you can enjoy them all summer long without worry.

How Do I Stop The Mold On Canvas Patio Furniture

Mold and mildew can be a problem for all kinds of outdoor furniture, but the canvas material on your patio furniture is especially susceptible to mold if not properly cared for.

Once it starts growing you’ll have a tough time getting rid of it without ruining the fabric.

Control Moisture

Mold will form on your canvas furniture because it absorbs the water from rain and dew. You should always try to keep this moisture off of your pieces by washing them with a garden hose or pressure washer at least once a month.

If you live in an area that gets lots of rainfall, be sure to give it a wash every week!

Use Bleach

If you don’t have easy access to a hose then another alternative is treating the mold with household bleach before scrubbing it away.

Just mix four parts of water into one part bleach and soak the affected areas for twenty minutes before rinsing them clean with plenty of fresh, warm water.

Let dry completely after cleaning since any standing moisture can cause more mold growth later on down the road.

Fabric Guard

There is a product called 303 Marine Fabric Guard that you can buy at any home improvement store which will prevent the mold from growing back on your canvas furniture for up to one year!

It’s worth it because not only does this make cleaning easier, but there won’t be as much scrubbing involved when you do have to clean off the mold in-between applications of 303 Marine Fabric Guard either.

Just spray all over your pieces and they’ll be protected against further growth throughout their lifespan.

Be sure to read the directions before using though since some types require being combined with water while others are ready for use right out of the bottle!

Silicone Spray

Spray your pieces of furniture with a silicone spray before placing them back outside. This will keep the mold from forming on top by preventing water from seeping into any surface cracks that may form.

Once you’ve sprayed it down, give an extra spritz every few days to ensure further protection against future growth!

Silicone sprays are readily available at most home improvement stores and can be used for all sorts of outdoor household items so you’ll have plenty left over if using this tip for other things as well.

Wipe It Down

A quick wipe down once or twice a month is not going to cut it when it comes to stopping the mold on your canvas patio furniture!

Storing Them

When you are done with your canvas patio furniture for the year, store it in a dry place out of direct sunlight and check to make sure there isn’t any dirt or debris before storing them away so they don’t get mold while being stored.

What Kills Mildew On Canvas?

If you are looking for a natural way to kill your mildew on canvas, then try using salt. Salt works well against mold and mildew because it absorbs the moisture in which these types of bacteria grow.

Using salt is an easy solution if you need something more than water alone will work but aren’t looking to buy any chemicals from a store or online retailer.

In addition, by simply sprinkling some salt on your problem areas before they start getting bad can sometimes solve them altogether!

You can also use warm water with vinegar mixed into it as another option that does not include buying materials at all either besides what you already have around the house like soap and bleach.

Mildew thrives in damp and humid environments. This makes canvases particularly susceptible because they’re typically made of cotton or linen fibers that absorb moisture easily.

Will Scotchgard Prevent Mold On Canvas Patio Furniture?

Scotchgard is a very effective and affordable way to protect items from liquids. However, it may not be the best choice for preventing mold on canvas patio furniture or other porous surfaces such as wood or wicker.

This type of material can easily absorb water, which includes Scotchguard treatment that you sprayed onto them.

So instead of protecting your outdoor pieces from moisture damage, they could become saturated with liquid and therefore susceptible to mold growth.


Be sure to follow our tips above regularly in order to prevent unsightly mold from appearing on your favorite pieces of canvas furniture. If you follow our advice, you won’t be disappointed!
