Cleaning a canvas tarp depends on whether it's treated or untreated. For untreated canvas tarps, you can generally wash them in a washing machine with gentle detergent.
Here's a more detailed breakdown:
Cleaning Untreated Canvas Tarps
Untreated canvas is more forgiving and easier to clean.
- Preparation: Remove any loose debris like leaves, dirt, or twigs.
- Washing Machine: Place the tarp in your washing machine. Be sure your washing machine is large enough to handle the tarp's size and weight when wet. Overloading can damage your machine.
- Detergent: Use a gentle laundry detergent. Avoid harsh chemicals or bleach, as these can damage the natural fibers of the canvas.
- Wash Cycle: Select a gentle or delicate wash cycle with cold or lukewarm water.
- Drying: You have two options:
- Clothes Dryer: Tumble dry on a low heat setting. Check frequently to prevent over-drying, which can lead to shrinkage.
- Laundry Line: Hang the tarp on a clothesline to air dry. This is the most gentle method and reduces the risk of shrinkage. Ensure the tarp is completely dry before storing it to prevent mildew or mold growth.
- Storage: Once completely dry, fold the tarp neatly and store it in a dry, well-ventilated area.
Cleaning Treated Canvas Tarps
Treated canvas tarps often have a water-resistant or waterproof coating. Washing them in a machine can damage this coating. Spot cleaning is usually the best option.
- Preparation: Remove loose debris.
- Spot Cleaning:
- Mild Soap Solution: Mix a small amount of mild dish soap with water.
- Application: Use a soft brush or sponge to gently scrub the affected areas.
- Rinsing: Rinse the area with clean water. Avoid soaking the entire tarp.
- Drying: Air dry the tarp completely in a well-ventilated area, away from direct sunlight.
- Re-treating (Optional): After cleaning, you may need to re-apply a water-resistant treatment to maintain its protective properties. Follow the manufacturer's instructions for the specific product you choose.
Important Considerations:
- Size and Weight: Always check the weight capacity of your washing machine before attempting to wash a large canvas tarp. A wet canvas tarp can be surprisingly heavy.
- Mildew and Mold: If your tarp has mildew or mold, treat it before washing. You can use a solution of white vinegar and water or a specialized mildew cleaner. Always test the cleaner on a small, inconspicuous area first to ensure it doesn't damage the fabric.
- Manufacturer Instructions: Always refer to the manufacturer's instructions for specific cleaning recommendations for your particular canvas tarp.
