Hey there! As a supplier of clear poly tarps, I've heard all sorts of questions from customers over the years. One of the most common ones is about how to remove stains from these tarps. So, I thought I'd share some tips and tricks that I've picked up along the way.
First off, let's talk about why stains happen in the first place. Clear poly tarps are great for a lot of things - they're waterproof, durable, and let in plenty of light. But because they're out in the elements a lot, they can get dirty. Whether it's dirt from the ground, bird droppings, tree sap, or just general grime from the air, stains are bound to show up eventually.
Now, before you start trying to clean your tarp, it's important to know what kind of stain you're dealing with. Different stains require different cleaning methods. Here are some common types of stains and how to tackle them:


Dirt and Mud Stains
These are probably the most common stains on clear poly tarps. The good news is that they're usually pretty easy to clean. Start by letting the dirt or mud dry completely. Once it's dry, you can use a soft - bristled brush to gently brush off as much of the dry debris as possible.
After that, fill a bucket with warm water and add a small amount of mild dish soap. Use a sponge or a soft cloth to dip into the soapy water and gently scrub the stained areas. Rinse the tarp thoroughly with clean water. You might need to do this a few times if the stain is really stubborn.
Bird Droppings
Bird droppings can be a real pain because they can be acidic and may damage the tarp if left on for too long. As soon as you notice bird droppings on your tarp, try to remove them as quickly as possible.
Put on a pair of gloves to protect your hands. Then, use a plastic scraper or a credit card to gently scrape off as much of the solid part of the droppings as you can. Be careful not to scratch the tarp.
Next, make a solution of one part white vinegar and three parts water. Soak a cloth in the solution and gently blot the stained area. Let it sit for a few minutes, then rinse the area with clean water. If the stain is still there, you can try using a mild detergent in warm water and scrubbing gently.
Tree Sap
Tree sap can be sticky and difficult to remove. First, try to freeze the sap. You can do this by putting an ice pack on the sap stain for a few minutes. Once the sap is frozen, it will become brittle and you can try to chip it off with a plastic scraper.
If there's still some residue left, you can use rubbing alcohol. Dampen a cloth with rubbing alcohol and gently rub the stained area. The alcohol should dissolve the sap. After that, rinse the area with clean water to remove any alcohol residue.
Oil and Grease Stains
For oil and grease stains, you can use a degreaser. There are many commercial degreasers available in the market, but you can also make your own at home. Mix a tablespoon of baking soda with a cup of warm water to make a paste.
Apply the paste to the stained area and let it sit for about 15 - 20 minutes. Then, use a soft brush to scrub the area gently. Rinse the tarp thoroughly with clean water. If the stain persists, you might need to use a stronger commercial degreaser, but make sure to test it on a small, inconspicuous area of the tarp first to make sure it doesn't damage the material.
General Tips for Cleaning Clear Poly Tarps
- Always test any cleaning solution on a small, hidden area of the tarp first. This way, you can make sure that the solution doesn't cause any discoloration or damage to the tarp.
- Avoid using harsh chemicals like bleach or ammonia. These can break down the poly material of the tarp over time and cause it to become brittle and tear easily.
- When rinsing the tarp, make sure to rinse it thoroughly. Any leftover cleaning solution can attract more dirt and cause more staining in the long run.
- After cleaning, let the tarp dry completely before folding or storing it. Folding a wet tarp can lead to mold and mildew growth.
Using the Right Tools
Having the right tools can make the cleaning process a lot easier. A soft - bristled brush is great for removing dry dirt and debris. A plastic scraper or a credit card can be useful for removing bird droppings and tree sap. Soft sponges and cloths are ideal for applying cleaning solutions and scrubbing gently.
