Unfortunately we do have a water softener but for some reason, there’s still buildup.

I’ve been seeing improvements with powdered bar keepers friend but it takes several passes and still comes back unfortunately.

What does the peroxide add? Whitening?

A common way to wash many dishes is a tub of soapy water to clean off food, a tub of diluted bleach water to disinfect, and a tub of water to rinse the dishes. It’s used by wilderness guides around the world.

I used epoxy and so far it has held up!

Where do you find citric acid? I’ve been using white vinegar in a jar in my dishwasher which gets rid of all water spots and cleans better with my hard water. However, I’d like to find a place to purchase citric acid crystals without relying on Amazon.

Thanks for the info, do you know what the fixes would be, short of replacing the tub?

Since I tried the liquid soft cleanser, will the powder be enough of an improvement to warrant purchasing?
