In order to get rid of any stains, you’ll need a can of the product. If you don’t have one already, you can get one from Walmart for about $6. To begin the process, simply apply it where any marks are, being sure to spray it at arm’s length. You should also ensure that you’re either applying it outside or in an area with plenty of airflow. This will help to ensure you don’t inhale the product. Once you’re happy with the area you’ve covered, simply work it in with an old rag or cloth. You can always apply more if you feel as though it’s necessary. Now, you just need to let it work its magic. After roughly 15 minutes, you should begin to notice that any marks should be long gone. If not, you can always repeat the same steps. When you feel satisfied, all you need to do is clean up the excess, and you should be able to use your patio doormat as usual.
The reason this hack works so well is because the WD-40 contains ingredients that help to dissolve stains, including those from your patio doormat. You can even use it to remove stains on your carpet, making it incredibly versatile. However, you should keep in mind that you may find residue in your doormat after using WD-40, so it’s probably best to try other solutions first (unless you don’t mind this).
