DH and I love this trick! Beats scrubbing bottles and lids, or drinking soapy water 'cuz you didn't rinse enough. A big box of tablets from BJs easily lasts us a year. One tab per bottle, and all of the lids in a big bread bowl with 2-3 tabs....
Thanks for the tip on cleaning VFFs with these! I wore mine in the shower last night to get the mud off, but denture tabs may actually clean them- I'm definitely going to try it!
