The Must For Rust...is magic as far as I'm concerned.
Dear Krud Kutter, My name is Andrew, I'm 19 and I'm a college student. Since December I have been working on converting a small, old bus into a camper. It's seen better days, and upon gutting it out I found quite a few deposits of rust. I ended up trying your product, The Must For Rust, and let me tell you that I am extremely satisfied. It works terrific on surface rust, and for thick rust it certainly gets the job done if you let it sit for a little while. I started off using it on the rims, then on random rusty areas on the body panels, and most recently the floor. This spring I plan on wire-brushing the entire undercarriage, followed by a nice spray coat of The Must For Rust, and then seal it off with some rust-proof enamel. For what it's worth, I work at a Home Depot in Minnesota, so I've been able to recommend The Must For Rust to several customers and even some co-workers. I've also mentioned it to several people online who are following my school bus conversion. If you're interested, you can see some of my own before and after pictures after using The Must For Rust on my bus's webpage, http://www.cardomain.com/ride/2973375 . I have no idea how you folks have came up with the formula for such a great product, but it's certainly worth every penny and is magic as far as I'm concerned. I wish I had a lifetime supply of the stuff because it works so well! Keep up the great work!
Sincerely, Andrew M.
...the water deposits...and other krud are down the sink...
I just want you to know that West Texas water is the worst element to get off on kitchen and bathroom sinks. Ater 35 years of marriage and fighting water deposits finally my marriage is successful and the water deposits of rust, alkalye, lime and other krud are down the sink. I will continue to buy from you. My house and H2O pipes were assemble in 1948.
Thank you from Debra in Knott, Texas
Rust was gone in seconds!
Hey, you guys are missing a fortune in sales ! Your product #MR32 (The Must For Rust) is absolutely fantastic....except, in my locale in the northwestern corner of Illinois it is VERY difficult to find.Â It should beÂ on the shelves ofÂ every hardware, autoparts, grocery and building supply store in America !Â I live in an area of huge iron amountsÂ in the water and have tried every product to remove iron stains from sinks, tubs, toilets, showers etc. with very little success.....by the way; there are very few products made just for iron removal, most are for lime and calcium deposits.Â Someone gave me a bottle of your product to try......and I was amazed. Rust was gone in seconds !Â I've since used it on tools, auto bodies, rusted bolts......anything with heavy or just a hint of rusts with 100% success.Â It is without doubt the best product for rust I have ever used !Â Being non-flammable, water based and biodegradable makes it even better.Â But it is VERY difficult to find. There is only one store within a forty mile radius of where I live that carries it and I buy-out their supply when they have it !Â Living in a rural farm community, I can assure you that rust is a big problem and virtually no one knows of the magic of your product. I have called a few local hardware stores to praise "The Must For Rust" , but I think your sales department is missing an huge opportunity for large distribution.
Good luck, Great product.
Sincerely, Don Caldwell
Cogratulations, you have a product that WORKS.
I have a stainless steel BBQ that sat outside in the eliments an had rust spots allover it. I tried CLR, Naval Jelly, Brillo Pads and a host of other products, nothing worked. I came across Krud Cutter The Must for Rust at Home Depot and bought a small bottle and used it as directed, also used a very fine steel wool pad #0000. THE RUST IS GONE. my BBQ looks brand new. I will be a user for life and pass the word on to friends.
Thanks again you have great product.
Wish I would have taken a before and after picture.

Directions for use:
Remove oil and grease from the metal to be treated. Rinse the metal to break the surface tension and wash away loose dirt. Apply the remover by brush, spray or by dipping. Use plastic, glass or stainless steel containers. Disassemble units composed of moveable parts before cleaning. Clean parts and allow to dry before reassembling.
DISSOLVING RUST FROM IRON OR STEEL: Apply the remover as required to penetrate the rust. Chemical action begins at once. Cleaning time will vary according to the rust. Medium to light rust will be dissolved in 30 minutes or less, while heavier deposits may require a second application.
ALUMINUM/CHROME: Apply the remover to wet surface. Allow time to clean, then rinse away with clean water, and buff dry with a cloth.
GALVANIZING: Where surface is unbroken, treat as suggested for aluminum. Where rust is showing at the surface, treat as for iron or steel. New galvanizing is properly prepared for painting by applying the remover and allowing to dry on surface.
BATHROOM/ SHOWER/TOILET CLEANER: Dissolves most calcium, lime and other hard water stains on porcelain, tile, fiberglass, and glass. Spray remover directly onto surface. Let sit for 5 minutes. Agitation with brush will speed penetration. Rinse away with water when stain is removed.
AUTO COOLING SYSTEMS: Removes oxides and rust when circulated in the system. When cleaning action is complete, flush system with fresh water and refill with coolant.
FIREARMS: Blueing is dissolved instantly by the remover.
IMPORTANT: Always test on an inconspicuous area first. For best results apply in ambient temperature of 70°F or above. On metal, maintain wet solution on surface to remove rust. Once the rust is dissolved, rinse or wipe the surface, and wait one hour or more before painting. Do not allow remover to dry on painted surfaces. For improved paint adhesion on clean metal surfaces, dilute remover 50/50 with water, apply solution, and rinse or wipe the surface. To use as a rust inhibitor on unpainted metal, allow the remover to dry on the surface after the rust is dissolved. The remover will then protect bare metal against rust for up to 12 months. Do not use on marble.

If swallowed, take large amounts of water. Do not induce vomiting. Get medical attention. Material Safety Data Sheet available. KEEP OUT OF REACH OF CHILDREN.
