You know, I finally bought the 5-lb tub of PBW.
I use a Tbls in most dishwasher loads. It has really made my glass sparkle, and the inside of the dishwasher is starting to get white again! this is important, as when we sell the house, the state of the appliances will make a difference.
I also have soaked the grungy out of the handle of my Kitchenaid food processor. If you have one, you know what I'm talking about - that stupid handle design with the lock mechanism, which gets all icky over time. I put some PBW in a large glass bowl, and submerged the handle in it, and then shook it occasionally. It's not perfect, but it is way better.
My glass teapot was so hazy, I thought the glass had been etched. PBW made it absolutely clear again. Also, I've rinsed the stainless tea strainers, and gotten a lot of built up residue off, which has made the screens have larger openings again (I'm baked, don't expect me to know the right terms), and look new.
I use PBW in my bubbler maybe once a week now. I also use this other stuff, One Step, which bills itself as a no-rinse cleaner (also for the brewing industry).. though I do rinse it like crazy.. I use this about once a week. The other times, I just do a hot water rinse.
I'm using the Nature's Answer Cranberry extract, about 3 or 4 drops in the bubbler water... and I try never to let it go beyond two days without at least a quick hot water rinse.
PBW is the best. Love this stuff. Rinse it well.
