I've lived in this house for 41 years and unfortunately we have never had a water softener. We have VERY hard water and proof of its existence shows on my showers tiles, my faucets, my coffee pot, my shower head....well, you get the picture.
Today I couldn't take it anymore and had to clean my shower tiles. I just didn't want to get the chemicals out of the basement and I thought, why not use my trusty old bottle of white vinegar. I sprayed the tiles, walked away for a few minutes and then began to wipe with a wet cloth. Tiles looked like new. There were a few that needed a little scrub with a brush but most came clean with just spraying.
I gave the shower head a little spray, cleaned the sinks with the vinegar and was done.
How have you used white vinegar lately?
