Here's some easy tips on how to clean your can.
- Empty your can.
- Drizzle a laundry soap that contains bleach, or a thick toilet bowl cleaner down all sides of your can.
- Put a bucket or two of hot water into the can.
- Let it sit for an hour or so so the steam and soap can do their work.
- Then empty your can and spray it with a small nozzle hose.
