Lots of good suggestions on this thread. Both Hubby and I have lung problems and have to be real careful. I rarely use commercial sprays, but Awesome is the exception.
I use white vinegar to which I have added a good squeeze of blue Dawn dishwashing detergent. This is in a quart spray bottle and I seem to tolerate the stream of cleaner for cleaning most surfaces.
DS and DDIL have moved into a new condo where the water is expecially hard. I hope the association will soon approve the installation of a water softener. Just think of the damage being done to the dishwasher, washing machine and plumbing. I am aghast at the visible damage already to the bath fixtures and faucets. I will try some of these suggestions. Thanks for sharing :-)
