This stuff is great. I should start off by saying my glassware gets pretty nasty. I am the worst when it comes to cleaning it. I bought this based on its reviews and I have to tell you I’m impressed! I didn’t need much of it at all and just swishing the product around inside of the glass for a few seconds got rid of the nasty thick grime that had built up. I’ve used other brands that require you to use much more product and require soaking for several hours. I will definitely be buying this again
