AstonishSpecialist Clean & Revive Foaming Powder for Tea Pots, Coffee Mugs, & Stainless Steel - No Scrubbing, No Residue (12.35 Ounce (Pack of 1))

WORKS AMAZING! HEAVILY STAINED STAINLESS STEEL THERMOS LOOKS BRAND NEW!

I have been using Astonish Clean & Revive for several years and will continue to purchase it as long as it is available. I have been using this product most often to clean my electric percolators several times a year. It works beautifully and the percolators come out clean as new. I will recommend Astonish Clean & Revive to everyone.

Awesome stuff for cleaning lots of stuff. Yea and coffee stained things become crystal clear.

This stuff is great. I like to use it in my Dutch oven. I use a couple of tablespoons of it and soak it overnight. The stains come out very well. I have tried homemade mixtures in the past, but nothing has compared to this.

I had read the reviews before I purchased this, but I still was amazed at how easy this was to get my insulated tumblers back to looking brand new. It took no scrubbing at all, just add the powder, fill with hot water, and let it sit. They are sparkling clean. I highly recommend this product.

I like how I didnt need a lot and it cleaned my tumbler immediately, without needing to wait. I drink tea in my cup, so it gets stained Everytimetrr. But this cleaner gets the job done and without elbow grease or using 1/2 the container.

This stuff really works. My mugs look brand new. I have it on auto order now.

Amazing - we used this at work to clean cups with a lot of sediment on them. Scooped the product into the cup/mug added boiling water and let it sit for a couple of hours. Every ounce of build up was gone!
