Using this trash bin cover is super easy. Just place it over your 41 - 50 gallon round trash can. The elastic holes on both sides help it stay in place. When it comes to cleaning, you can simply toss it in the washing machine and tumble dry on low heat. But be careful not to use high heat as it might damage the spandex material. Also, avoid using harsh chemicals or bleach when washing. This cover is great for weddings, parties, and other events, so keep it handy for those special occasions. It will keep your trash cans looking neat and presentable.
