While these stains don’t come out with regular hand-washing or stints in the dishwasher, there are a few different things you can do lift them. Which one is best and easiest? I was determined to find out! So I tried five different methods and recorded my results. Here are my findings.
How I Tested the Methods for Cleaning Coffee Stains Inside Mugs
I rooted around in the cabinet and found my five favorite mugs, which, with near-constant use, also happened to be the most stained. I brewed a strong batch of coffee and poured about two ounces of liquid in the bottom of each one. Then, I let it all sit on the counter to soak in. Once the liquid had evaporated and the coffee oils had left a nice, tough layer on top of the already-lingering stains, it was time to get to work by cleaning each one using five popular and proven methods!
The ratings: I ranked each stain-removal approach from 1 to 5, with 5 being the easiest and/or most efficient and 1 being the hardest and/or least efficient.
