I notified the seller, they replied promptly, and I had a great interaction with a friendly man. They contacted the shipping company, and the nice man then notified me they were sending out a new one the next day, which they did. Nice people at Alliance Chemical. The acid itself is great. For any blueberry growers reading this, I use it to lower the pH of my alkaline well water before watering the bushes. Works great, and it doesn't take much. This gallon of 85% phosphoric acid lasts almost three times as long as a gallon of pH down sold for hydroponic use. Review: Great for rust removal - I bought this product to remove rust from steel as a part of a refinishing process. It worked absolutely great! I'm very pleased. Now keep in mind, this is a liquid. It will be most convenient to use on horizontal surfaces. But, it has enough viscosity that you could probably use a cheap paintbrush to brush a thin coat on vertical surfaces too. However you do it, if you keep this material on rust, the rust will disappear. ## Features - HIGH-STRENGTH 85% CONCENTRATION: Our Phosphoric Acid 85% Technical Grade is a concentrated solution for industrial needs requiring high-strength acid. - EFFECTIVE PHOSPHORIC ACID CLEANER: Proven to remove rust and scale, this product is an essential tool for maintaining and restoring metal surfaces. - INDUSTRIAL PH ADJUSTMENT: Highly effective for pH level management in diverse industrial chemical processes, water treatment, and metal treatment. - AGRICULTURAL UTILITY: Acts as a vital component for agricultural productivity, serving as a nutrient source for professional fertilizer manufacturing. - PROUDLY MADE IN AMERICA: Alliance Chemical ensures rigorous packaging standards for safety and quality, maintaining product integrity for bulk use. ## Technical Specifications | Specification | Value | |---------------|-------| | % Assay of Chemical(s) | 85 | | ASIN | B0832B9QJ9 | | Brand Name | Alliance Chemical | | Container Type | Bottle | | Customer Reviews | 4.5 4.5 out of 5 stars (69) | | Included Components | Chemical | | Item Form | Liquid | | Item Weight | 82.4 Pounds | | Manufacturer | Alliance Chemical | | Volume | 5 Gallons | ## Product Details - **Brand:** Alliance Chemical - **Item Volume:** 5 Gallons - **Item Weight:** 82.4 Pounds - **Package Information:** Bottle - **Percentage assay:** 85 ## Images ![Alliance Chemical Phosphoric Acid 85% Technical Grade - 5 Gallon Pail - 85% Phosphoric Acid Cleaner for pH Adjustment and Corrosion Inhibition - Made in America - Image 1](https://m.media-amazon.com/images/I/616J0Wy8f1L.jpg) ![Alliance Chemical Phosphoric Acid 85% Technical Grade - 5 Gallon Pail - 85% Phosphoric Acid Cleaner for pH Adjustment and Corrosion Inhibition - Made in America - Image 2](https://m.media-amazon.com/images/I/51sNNvYla1L.jpg) ![Alliance Chemical Phosphoric Acid 85% Technical Grade - 5 Gallon Pail - 85% Phosphoric Acid Cleaner for pH Adjustment and Corrosion Inhibition - Made in America - Image 3](https://m.media-amazon.com/images/I/61JDTNqIgpL.jpg) ![Alliance Chemical Phosphoric Acid 85% Technical Grade - 5 Gallon Pail - 85% Phosphoric Acid Cleaner for pH Adjustment and Corrosion Inhibition - Made in America - Image 4](https://m.media-amazon.com/images/I/61LpwBkSF6L.jpg) ![Alliance Chemical Phosphoric Acid 85% Technical Grade - 5 Gallon Pail - 85% Phosphoric Acid Cleaner for pH Adjustment and Corrosion Inhibition - Made in America - Image 5](https://m.media-amazon.com/images/I/51riSbXEroL.jpg) ## Available Options This product comes in different **Model** options. ## Questions & Answers **Q: will this leave a zinc phosphate coating when cleaning rusty metal?** A: no it doesn't clean the rust it will turn the existing rust from Iron 2 oxide to the more stable iron 3 phosphate which converts the rust to ferric phosphate in other words the black stuff after applying it to the rust. it prevents the formation of new rust by acting as a barrier as long as you manage to to convert all the rust. any non rusted metal will not get this coating. the most common way to get a zinc phosphate coating is to use electroplating using electrolysis. this product is most effective if you remove some of the thicker rust mechanically by sanding or using a wire brush so the phosphoric acid pernitrates most of the rust to convert it all. after that use something like por15 and an epoxy primer to protect whatever metal you are trying to treat. have done this to a few of my cars and used the product on other rusty metal objects and it prevents new rust from forming as long as you do not damage the surface coating and expose bare metal and you manage to convert all the rust. that's why cleaning as much of the rust off as possible and thinning out the rust yields best results. **Q: Can you paint over it?** A: Use Phosphoric Acid diluted to 20% (200ml/litre. Apply to surface for 5-30 minutes to remove light film. Soak very rusty items for days with periodic agitation. Rinse with cold water., let dry, wipe clean metal with solvent, acetone, let dry apply primer **Q: Does this need to be diluted to use as a rust converter?** A: YES! About 3 parts water to 1 part Phosphoric acid. Watch whatever you are cleaning, Do not leave object in solution for long periode of time! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great experience with the seller *by A***R on December 27, 2024* A long overdue review, the package the gallon of acid I ordered was damaged during transit, and the shipping company informed me that they would not deliver it and were going to dispose of the contents.
