A little over a year ago I purchased a Mukoko 20 oz Stainless Steel Vacuum Insulated Mug. I like a big cup of coffee in the morning and I have to admit I love this mug. I had grown tired of my coffee getting cold and this mug keeps it warm a long time even when not using the lid.

What I haven’t loved is the coffee stains that ended up lining it. I tried vinegar, Bar Keepers Friend, and a variety of other cleaning options and nothing really cleaned the mug. It stayed stained.

Then I tried denture tablets. It required some experimenting before I found the perfect combination. This morning I boiled water in my kettle, added a little to the mug, dropped in 4 (yes, I said 4) tablets and added boiling water until the foam was at the top. I let the foam die down, stirred it around a little, and then topped off with boiling water until the mug was completely full and let it sit for about an hour.

I couldn’t believe how great the mug looked when I dumped the water/denture tablet solution out. There was just a little film that was easily removed by a melamine sponge.

I wish I would have taken a before picture to show how nasty the inside looked but this is how it looks now. It looks like it did when I took it out of the box at least 700 cups of coffee ago. I can’t wait to have coffee tomorrow.

Note about melamine sponges: I quit paying the outrageous prices at grocery stores for magic erasures a long time ago. Just research melamine sponge on Amazon and you can purchase a quantity at very reasonable prices and they clean just as well.
