Dollar Tree Tub and Shower Cleaner

The iron is so bad in our water that I have to clean our shower once a week. There are two things that work for me. The first is "The Works Tub & Shower Cleaner" from the Dollar Tree. I have to used between 1-5 bottles depending on how bad it is. You spray it on, leave it for 19 minutes, and wipe off. It's magic.

The second product that works is "Iron Out" but it has to be in the spray bottle for it to work on my shower. It's pricey and sells for about $8.00 a bottle. You spray on and voila! It magically comes off. No scrubbing or anything.

Good luck!
