Best DIY Way to Clean a Coffee Mug
If you’re familiar with DIY cleaning, then you won’t be surprised by the secret ingredient for cleaning coffee mugs: baking soda. Yep, it seems the magic of baking soda knows no bounds. Your stained drinkware is no exception! Sprinkle a bit of baking soda directly into the mug, and scrub with a damp cloth. The abrasiveness and cleaning power of the baking soda should wipe away the stains without much effort. Rinse thoroughly.
Best Store-Bought Mug Cleaner
According to happy Amazon reviewers, Astonish Cup Clean works wonders on coffee stains. The product is made with sodium percarbonate, also known as oxygen bleach. Here’s how it works: You add one teaspoon of Astonish to your stained mug, fill with hot water and let cool. Then, rinse with cool water. No scrubbing needed!
One Astonish reviewer said, “I’ve got a coffee travel mug I’ve never really cleaned well, it’s over a year old. Hadn’t really noticed how bad it had become. Used this Astonish cleaner, wow! Within 10 seconds of putting the hot water in the mug with the powder already in there, old coffee slime was bubbling out in the foam. Mug came out spotless with one use.”
This Amazon product works to clean travel coffee mugs, too.
The Most Surprising Mug Cleaner
This mug-cleaning idea involves dental care; specifically denture tablets! It makes sense if you think about it, dentures are commonly made from the same material as your coffee mugs—porcelain.
Here’s how to clean a mug with a denture tablet:
- Fill the mug with warm water and add a denture tablet.
- The tablet will fizz as the cleaning action begins.
- Wait until the fizzing stops and then rinse clean.
