Phosphoric Acid 75% | Food Grade | 1 Gallon | Rust Remover, Etch, Delimer

I worked for a company that supplied proprietary chemicals to the food and metal working industries. We used food grade phosphoric acid to remove lime scale, hard water stains, rust, etc. It works well when cleaning out your humidifier, coffee pot and many others. Many jobs will not require using the product a full strength. This product is easy is mildly acidic, easy to handle and works great.

We use phosphoric acid to balance the pH in our hoophouses. Since we use well water to irrigate inside the hoop houses, the pH needs to be balanced occasionally. This product is easy to use and we see results very quickly. I would recommend this as an economical, simple method to balance pH.

Purchased this product to electro polish stainless steel welds, worked out awesome!

Ordered this product to remove rust from a twenty year old industrial kettle that was made of stainless steel. I had never encounter “stainless” that was so bad.Product exceeded all expectations.Was not an instant job, needed some elbow grease, but the end result was better than expected.

great

I will be using this to measure PH in water levels, much cheaper than buying the pre-made.

Seems to be what the label says. Good quality stuff works for electropolishing die cast.

Great stuff
