The popular lubricant is the perfect solution for stubborn stain
WD-40 is a popular lubricant, well-known for penetrating through metal parts and reducing friction. In addition, it protects from rust and moisture. WD-40 can also remove stubborn stains like grease, tar, and glue.
Nobody ever thought before that this product could be used to clean toilet bowls, though. In fact, it can remove a stubborn stain with amazing results.
Give a squirt or two. Wait a few minutes, then wipe with the toilet brush. Follow up with your favorite cleaner, if you like. Flush it and the results will be amazing.
Anyway, don’t overdo because this product’s main application is not cleaning toilets, but it also works well for that.
