WOOHOO, looks great guys!! While I love the solid-tub Frigidaires, there's something about the 1-18's that makes them a LOT of fun to use...could it be that they pulsate 30 PPM faster and have that loud "CHUG-CHUG-CHUG" sound similar to a diesel engine?
For hard water stains, I've had awesome results with Easy-Off BAM. However, like Greg said, hard water tends to etch glass...it's happened to my Dual-Tumble and I wondered why none of it came off. Although when you get a good amount of water or suds splashing up on the window you can see in normally.
