Debby,
I saw a commercial for one. It's a little device t hat hangs in your shower and at a touch of a button when you are finished with your shower, you push it and it circles all the way around with a cleaner fluid and rinse. Wouldn't work with my set-up.
RE: mold
We did pull out our old, old shower and tile, hubby replaced it this summer. I am allergic to mold.........although not severely. It's one of the major sinus infection triggers for me, though. Keep in mind the house is old and the previous owners did a lot of very bad "work" and add-ons when they lived here!!
I have felt much better since that.......but battling dust up on this windy ridge is a losing battle!!! I just keep waaaaaaaaaaay less knick knacks now!!!
We have an ionizer in our bedroom for some of the dust control, and it does help. Hubby has one at the office as he does have more allergies to pollution and it does make a difference big time!!
Yep..........balance and just doing what works for you is the key!!!
