Coffee grounds are a great addition to compost because they add nitrogen to the soil.
Don’t use a metal scrub brush, as this could be too harsh on your filter.
Coffee grounds also help to ward off mosquitoes.
Try not to rinse a ton of coffee grounds down your drain to avoid clogging it. A little bit here and there is fine, but if there is more than 1 tbsp (15 g) of grounds in your filter, try to scrape them into the garbage instead of your sink.
For example, try using 1 cup (240 mL) of vinegar and 1⁄2 cup (120 mL) of water. If you don’t have a big enough bowl, consider filling up your sink with water and white vinegar instead. White vinegar is a natural cleaner that will kill germs without exposing your filter to harsh chemicals.
While you’re waiting for your filter to soak, you can clean the rest of your coffee maker with white vinegar and water.
You can deep clean your coffee filter with vinegar about once a month.
