Deep Cleaning the Zojirushi Stainless Steel Mug

Courtney and I use our Zojirushi stainless steel mugs every day. I have the 16oz model with SlickSteel interior and use mine for coffee while she has the 20oz model with non-stick interior which she uses for water since we have a professional liquid spiller on duty 24/7. We LOVE these vessels as they keep our drinks hot for hours or cold for days and keep spilling to a minimum. The only complaint I have about the Zojirushi mugs can’t really be registered as a formal complaint as it all has to do with how I care for my mug (or the lack of care in this case). I tend to leave my empty or nearly empty mug in my bag or on the counter overnight during the week more often that I’d like to admit. Recently I noticed that my (artis-anal) coffee was sour and the inside of my mug was coffee stained and was no longer that beautiful polished chrome steel that I originally unpacked. I turned to the internet and found I wasn’t alone. While the image below is 10 stages beyond what the inside of my mug looked like, I was seeing similar staining as the bottom of the mug in this picture.

“That’s dis-gusting”.

I know you’re thinking it and I couldn’t agree more. With that said there is the issue of how to clean these mugs when they get stained. I started to take a crack at it and found myself getting nowhere when I tried due to two factors.

  1. Washing the center and bottom sections of the inside of these mugs is a major PITA. I broke a spatula handle by applying more pressure than it could handle in my attempts to clean it.
  2. The stain can become partially infused and layered onto the stainless steel of the mug.

After 30 minutes of dish soap, paper towels, elbow grease and scalding hot water I had barely made a dent in the overall staining and wanted to give up on trying. Then I realized I had a cleaner that no stain or dirt is immune to and that it just might be worth a shot to bring out the big guns. Yes, of course I’m referring to an extra strength Mr. Clean Magic Eraser! I gave it a dunk in scalding hot water and forged ahead full strength in my attempt to restore my beloved coffee mug as replacing it isn’t an option due to it’s unique branding.

After another 45 minutes of continual washing, rinsing and repeating I was able to get my mug back to full health and beauty. This worked like a charm and was a mere dollar worth of hardware[1].

So fresh and so clean

As long as you follow up with a dish soap hand wash and multiple rinses you should be golden using this method if your mug has gotten stained from long term use. I’m no longer risking this possibility and am cleaning my mug nightly which takes a mere 60 seconds of my day to do. I’d recommend doing the same.

  1. If you don’t count the spatula that gave it’s life in service of a greater good.  ↩

Joey Roth Rethinks the Moka Pot

Joey Roth and Blue Bottle Collaborate to create the mokapot

Joey Roth first came onto my radar in 2010 when I was really into tea. Kevin Rose sat down to talk with Joey about his beautifully minimal tea kettle, the Sorapot. While I really wanted one I didn't succumb to my desire primarily due to the $300 price tag. Since the Sorapot, Joey has designed and released letterpress prints, self-watering planters, lust worthy ceramic speakers, and version 2 of the Sorapot. I've followed Joey's career as he continually brings a fresh perspective on existing products and marries form and function at a level comparable to Jony Ive's design aptitude. Earlier this week Joey unveiled his newest creation and it's all about crafting the perfect cup of coffee directly on the stove. Joey has been working for nearly two years to refine the design and improve the functionality of the moka pot in a way that only he can. He's partnered with California based Blue Bottle Coffee as the exclusive distributor for the moka pot. I look forward to reviewing this new take on making a great cup of coffee when my moka pot arrives in the next week or two.
