It's works like Lime Away, only it's called
THE WORKS. You can get it at the Dollar Tree. Just don't get it on any metal like your faucets.
I don't like to spray it on because of the fumes. I soak it on an old cloth, wipe it on, wait 1 minute and wipe it off, no elbow grease needed.
I keep it in both my bathrooms because my grandkids are pigs when they come in to take a bath at night.
The kids, 4 of them, are grounded this week because they took a shovel out of the garage and dug a 3 foot wide, 3 foot deep hole in my yard. They were looking for treasure. I wouldn't let them in the house, had to hose them off outside before they could come in.
