“Not OP, but I use denture cleaning tablets for all my glass/steel emotional support water bottles and all my partner’s coffee/tea mugs. I pop one in the bottom, fill it with some warm water (leave a little room at the top since it will bubble), replace the top, and let it sit for about 30 minutes to an hour. After time elapses, I give the glasses a couple of good shakes, empty them out, rinse them, and dry them upside down. I thrifted a bottle mat that works great for making sure moisture doesn’t get trapped at the bottom. I rinse my straws after every use, but weekly, I’ll throw them all in a glass canister along with a tablet or two and do the same process as the bottles I also use a couple of tablets in my sink/toilet bowls if they look a bit rough. I let them sit for about 20 minutes before rinsing/using a brush to remove any stains. There are no harsh smells like a lot of other bathroom cleaning products.”
