not 100 removal of yellow lines

THIS STUFF WORKS GREAT !! MUCH MUCH BETTER THAN --( THE WORKS )

Powerful lime cleaner for sure

I cannot go into a home for the first time without with product...hard water corrosion just evaporates in seconds. Immediately rinse for safety. This product will eat stainless if not used properly.

works well

Works really well!

Great product

Very Effective product.

It is a commercial strength cleaner. It was recommended by the cleaning crew where I used to work. I wear mask to use the product and follow instructions and little logic to get heavy stain out. But no more heavy stain after using this. It will work for you. The cons, you have to buy a whole box of 12 pk and only get 1 brush. This will probably last me 10 years and a few more brusher for 3 toilets to clean.

Excellent paper towel for the money
