Manufacturer Remedy Information This item is hazmat, it was not part of a safety recall and can be carried in PHL4. -Daniel Brock Original ticket: tt 0005095838 From the Manufacturer America's Favorite Rust Remover, The Must for Rust removes & prevents rust in one step! The proprietary formulation penetrates every void of a metal surface and dissolves rust/oxidation through chemical action. Then tiny, rust-inhibiting crystals are formed and become integral with the surface molecules of the metal to resist future rusting. The corrosive agents attach these crystals instead of the metal. Once completely dry, the surface is ready for the nest step, whether it be painting, welding, plating, lubrication, etc. Or simply leave the surface bare, and the crystals will inhibit future rust formation. Krud Kutter's Must For Rust is ideal for painting. When dry, the Must For Rust accepts any primer, paint, coasting, etc, and provides a clean surface free of contaminants, which allow a secure bond for coating. When chips or breaks appear in the coating the surface underneath will limit the rust to the break. That means that rust won't spread under the coating and maintenance thought up will be quick and easy. Easy to Apply with spray, brush or dip. Rid Rust with Must for Rust. Review: This Stuff is Pretty Fantastic! But Some People Just Don't Get It... - This stuff is pretty awesome (if used properly)! it literally dissolves away rust. It may take a few applications of this spray along with some scrubbing and washing but it does definitely work. The problem: If many people are anything like my roommates, they assume that this spray is just magic and will make a super rusted old car look brand new. It's not magic. That doesn't mean that you can't remove a lot of rust from something, It just removes rust little by little over a period of time and possibly several applications. So far I've used this stuff to de-rust some of my car parts (just spraying it under my car every 15-20 minutes several times), bike parts, metal light switch covers, tools and as shown in the photos attached, some cabinet hinges, shower head and other metal parts in my bathrooms (and many other metal parts). Unfortunately I didn't take before and after photos of everything I've de-rusted but these hinges and the shower head only got a single application and this is what they looked like ~15-20 minutes later. Like I said, it definitely works. If you've got something that's VERY rusted, you might want to get the gallon container of this and put it in a bucket (along with your rusted part) to let it soak. I've also dumped it into my ultrasonic cleaner and that works REALLY well. Removes every bit of rust. If you can't submerge the part, then just give it several applications of this stuff, keeping the part wet for the most part. And then scrub and clean it in between to see its progress. I should also mention that I've now gone through at least 5 different "rust-removing" agents and none of them (besides straight up acid [which is dangerous]) have done as good a job as this stuff. Only downside is probably the smell. Spray it in a well-ventilated area if possible and after you remove the rust, rinse it, try it with a towel, give it an hour to dry the rest of the way and then coat it in something like "Sta-Bil rust prevention spray or something (if possible) to keep it from getting rusty again. Bottom line: It's my new favorite rust removing chemical! Love this stuff :) Review: It really works well but takes patience if it's a large item. - I bought this to clean two steel hollow rods used on a radio antenna system. The Antenna was bought second hand and while 90% of it was aluminum those two 10 ft rods were steel and had been left outdoors on the ground for 5 years. Yep they were completely rusted and flaking. Taking them out to the driveway I wire brushed off all the flaking rust and then applied the Krud Kutter. The problem with doing large parts is that you cannot soak them in a container so you have to just spray them then let it sit for 30 minutes and then spray them again because the Krud Kutter will dry out. After 4 applications with an in between wash after the first two and then a final hosing off I had clocked about three hours working on them. The end result was at first a mixed bag of very clean shiny galvanized metal and patchy areas of darkened metal. On closer examination I realized it was not rust but just a left over stains that might come out with more soaking time. I decided instead to just use some 250 grit sand paper and rub it down lightly for 5 minutes. The once completely rusted surface was now 90% smooth and was left with just some small 1mm round pock marks on 10% of the surface from deep rust penetration. After cleaning off the rods with pure Alcohol I quickly sprayed the surface with cold Zinc spray. You really need to put something on the surface fast because if you leave exposed you can see a light powdery rust layer forming within minutes. After the cold zinc was sprayed and it dried I was shocked that I could clearly see the part numbers stamped into the metal, they looked as clear as if it was new! These were not even remotely visible before the treatment and I am pretty sure if I had used a hard sander they would have been rubbed out along with a lot of the surface steel. After giving the cold Zinc 48 hours to cure I used an epoxy paint that would hold to the cold Zinc Primer. The end result was almost a factory look as the paint filled out any tiny pits that were remaining. I am very happy with this product, it does what it says it will do and is better than any rust removal chemical I have used before. It does not eat at the metal, only the rust. ## Features - Unique rust remover and inhibitor removes and prevents rust in one step - Water-based formulation penetrates into every void of a metal surface and dissolves rust/oxidation through chemical action - Easy to use spray on application allows for completion of small projects quickly and soak in for larger projects - Wipe or rinse following use to provide a paint ready surface and create secure bond for topcoat - Protects bare metal from rust for up to a year ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000F6UHDY | | Age Range Description | Teen | | Best Sellers Rank | #249,283 in Health & Household ( See Top 100 in Health & Household ) #2,974 in All-Purpose Household Cleaners | | Brand | Krud Kutter | | Brand Name | Krud Kutter | | Color | Colorless (Black color code: 000000) | | Color Code | 000000 | | Container Type | Bottle | | Coverage | 12 sq. ft. | | Customer Reviews | 4.3 out of 5 stars 750 Reviews | | Dry Time In Hours | 1 | | Finish Type | Gloss | | Full Cure Time | 1 Hours | | Global Trade Identification Number | 00618818406015 | | Included Components | Unit^Instruction Guide | | Is Waterproof | False | | Item Form | Liquid | | Item Type Name | KRUD KUTTER MR32 The Must For Rust, 32-Ounce Trigger Spray | | Item Volume | 946 Milliliters | | Item Weight | 2.33 Pounds | | Manufacturer | KRUD KUTTER | | Model Name | Not Available | | Model Number | MR326 | | Paint Type | Specialty | | Part Number | MR326 | | Size | 12 Fl Oz (Pack of 1) | | Special Feature | Non Toxic | | Special Features | Non Toxic | | Specific Uses For Product | Interior/Exterior | | Surface Recommendation | Metal | | UPC | 618818406015 | | Unit Count | 12.0 Fluid Ounces | | Water Resistance Level | Water Repellent | ## Product Details - **Brand:** Krud Kutter - **Color:** Colorless (Black color code: 000000) - **Finish Type:** Gloss - **Item Volume:** 946 Milliliters - **Paint Type:** Specialty - **Size:** 12 Fl Oz (Pack of 1) - **Special Feature:** Non Toxic - **Specific Uses For Product:** Interior/Exterior - **Surface Recommendation:** Metal - **Unit Count:** 12.0 Fluid Ounces ## Images ![KRUD KUTTER MR32 The Must For Rust, 32-Ounce Trigger Spray - Image 1](https://m.media-amazon.com/images/I/81Zff8w2anL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This Stuff is Pretty Fantastic!

It is so watery it won't actually cover the item as a thin film, but rather forms little droplets of de-rusting chemical, so those little circles where the drops are will benefit, but the rest of the item will get no treatment. I found the only realistic way to use this is to pour it into another container and immerse the item to be de-rusted in that. This doesn't work super fast, & I find 10 minutes at a minimum are needed. After that, you'll need to buff off the light coating of dark oxide that remains on the de-rusted item (I use a finishing pad. You'll then have a nice, shiny, de-rusted item. This product is made by Rust-oleum, & they have another product that squirts out as a gel and that is REALLY good at staying put and de-rusting. You can even trowel it around with something, spreading it where you want it in case the spray wasn't uniform. ## Frequently Bought Together - KRUD KUTTER MR32 The Must For Rust, 32-Ounce Trigger Spray - CRC Evapo-Rust, Heavy-Duty Rust Remover, Reusable, Acid-Free, Non-Corrosive, Water-based, 32 oz, Removes Rust to Bare Metal - Rocaris 6 Pack Carbon Steel Wire Wheel and Pen Brush Set with 1/4-Inch Hex Shank for Rust Removal, Corrosion and Scrub Surfaces --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/4926904-krud-kutter-mr32-the-must-for-rust-32-ounce-trigger](https://www.desertcart.pt/products/4926904-krud-kutter-mr32-the-must-for-rust-32-ounce-trigger) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-10*
