The Vinegar Solution
My dishwasher is OK. They don't sell the really good ones here, so mine is top of the line.....for Chile. It doesn't rinse very well, so I always must use the special rinse liquid, which is expensive.
I had read on several blogs that you can substitute vinegar for the pricey liquid, but I am often skeptical of amazing claims. But, I figured, what could be lost if I tried it? Nothing! So I squirted the vinegar in. You may not believe this, but it works better than the pricey stuff!
Not very "wow!", but the long-term savings means that I can actually use my dishwasher more often. Now I can hear a hearty "Amen!" from chief dishwasher, Eileen.
