one quart will last months in my operation

As a homebrewer I've been using lactic acid to adjust the ph in the wort of some recipes. My palate is sensitive to lactic acid. I started using using this phosphoric acid and have been very pleased that I'm no longer getting that unpleasant taste.

I need this to clean glass vases and tea/coffee stains from cups, as our water is very "hard". It does help, but not enough. It is a strong, dangerous chemical, so be careful. Use outside.

Works good, don’t need much. I use it to stack lines

Used this in a recipe to make a rust converter, I was surprised that it worked. Be sure your using PPE.

Awesome... I would buy this again

I bought this product to clear away toilet scum, but it does not do the job. Calcium cleaners used to contain this product, so I thought it would work, but not. I am sure it would be useful for other things though. My rating is based only upon the fact that it does not clean toilet bowl rings.

Great product. Most of these PH control liquids are 50-70%. This stuff goes a long way.

Dilute 85% phosphoric acid with equal parts water and spray on anything rusty and leave for 24 hours. It completely neutralizes rust and allows you to undercoat. Works like magic on restoring cars or trucks. Can not recommend this product highly enough.
