My poor, poor travel mug. It used to be an absolute stud. Kept coffee hot for hours. Never spilled. Was easy to clean (or so I thought). And the coffee tasted great.

Until that one dreadful day. I remember it vividly: I took a sip from my travel thermos to be met with a taste that was nothing like coffee. It tasted like plastic/some weird kind of detergent.

“Great…” I thought to myself, “now I'm going to have to get a new travel mug.”

Well, I'm sure glad I didn't do that. You see, I have this handy dandy solution called Cafiza. I got it for Christmas, and even though it's labeled as an espresso machine cleaning solution, it worked amazingly well on my thermos.

That icky un-coffee-like taste that the mug was emitting is completely gone now. Supplanted by delicious coffee flavors and aromas.

So here's what you gotta do to clean anything that comes into extended contact with coffee and leaves a lingering stale coffee, plastic, or detergenty taste behind.

Step 1: Get a hold of Cafiza

It comes in tablets, powder, and other forms I believe, but it's probably all the same product. I have this one.

It's more expensive than white vinegar, but a little goes a long way and to be honest, I think this is more effective by far.

Step 2: Put a tablespoon of the solution in your carafe or mug

Honestly, I just sprinkled a little bit into my mug. But if you want to be precise, follow the instructions on the back of the bottle.

Step 3: Add warm water and let sit for half hour

Pretty self explanatory, no?

Step 4: Dry and enjoy

I should mention that you will need to give it a few rinses before drying, but you already knew this!

Since my Bonavita's carafe is in serious need of a cleansing, I thought I'd give you a run down of how to use the Cafiza.
