That's a common and frustrating problem! A stained white plastic bin can look unsightly and even hold odors. Don't worry, with the right approach, you can often restore it. Here’s a natural, step-by-step method I use.
First, empty and rinse the can thoroughly. For a fresh, organic stain, a mix of baking soda and water into a paste often works wonders. Scrub it on, let it sit for 15-30 minutes, then rinse. Baking soda is a gentle abrasive and deodorizer.
For set-in or mysterious stains, a stronger solution is needed. My go-to is a diluted bleach solution (1 part household bleach to 10 parts water). Always wear gloves and work in a well-ventilated area. Apply the solution to the stain, let it sit for 5-10 minutes—no longer, as bleach can damage plastic over time—then scrub with a stiff-bristled brush (not metal, as it can scratch) and rinse extremely well.
If you prefer to avoid bleach, a paste of hydrogen peroxide and baking soda is a great alternative. Apply, let it sit for an hour or even overnight for tough stains, then scrub and rinse. White vinegar can also help with mineral deposits or odors; just spray, wait, and rinse.
The key is to act quickly on new stains and to give any cleaner time to penetrate. After cleaning, a regular wipe-down with a mild soapy solution can prevent future stains from setting. Hope your bin looks brand new again soon
