I had been just using cleaning strength vinegar when cleaning my coffee maker. I thought I would try this product because I love my coffee maker and use it daily. This descaling solution is amzing! I couldn't believe how much scale was in the filter. I ran water through a few times afterward to make sure all the solution was gone. When I made the next pot of coffee...WOW! I can't tell you how much better the taste was...so much better! This product is a MUST for coffee drinkers.
