Fit Fruit & Vegetable Wash, Soaker/Refill Bottle, 32-Ounce Units (Pack of 3)

I cannot say enough good things about this product! It does a superb job on my produce, but I've also discovered that it's great on my cast iron, (no matter what I've cooked on it). I just fill it with the hottest tap water and add about a teaspoon of FIT. 

After a two-minute soak I gently swish with a scrub brush and it's clean. Rinse, and the brush looks like new again too. Before I dump it out, I dip a cloth and and clean my stove-top as well. 

The FIT solution cuts right through the grease! The first time I did this I noticed how sparkly-clean my rings were afterward, so now I use it in my ultrasound jewelry cleaner too. The list just keeps growing, to the point where I now use it to clean just about everything!
