[Princess Auto] Krud Kutter 'The Must for Rust' Rust Remover 3.78l -- $14.99!

Princess Auto has 3.78 litre jugs of Krud Kutter 'The Must for Rust' rust remover for $14.99. I've never seen it priced this low anywhere, and compares to 946ml for $15.99 at Home Depot or Canadian Tire.

Excellent product that I've had great success with this summer for automotive rust removal use. Tested one of the best on Project Farm as well. Jugs were located in the automotive section of the surplus aisles.

Since I didn't want to spend that much on rust removers, I soaked the rusted brake parts in household vinegar overnight and it worked just as well - $4/gal and vinegar is pretty safe to work on, use nitrile gloves though because rust will also stick to your hands. I then put the parts in a solution of baking soda before rinsing with water and drying with a cloth. If you take the parts out of the vinegar, surface rust will form almost immediately.

I hear a molasses solution works just as well, but I have never tried it myself. Was waiting for him to drop a rim on his toe but it didn't happen...

That's a pretty good deal, I bought like the 1L or something version for around the same price from CDN tire not too long ago. Product works great

Haha. Thank you, mine did indeed rust immediately. Granted, vinegar didn't dissolve all of the rust anyways, so I wouldn't have used them in the end.

LOL about waiting for him to drop the rim on his toes - crazy to work in bare feet like that.

Thanks for this - I wasn't aware of molasses having the same effect so I'll look into it more. I neglegted checking my e-brakes for about 5 years while maintaining only the regular brakes every year and was caught off guard with the amount of rust forming in the rear disc hat. I restored and painted the e-brakes springs and hardware after removing the rust with white vinegar.

I did the same thing with the rusted garage door opener sensor clips at the bottom of the door rails. Without doing that those clips would have corroded beyond repair soon.

Vinegar will remove all the rust eventually, you might need to let it soak longer depending on how badly the rust is. I let some of the rust soak for a few days to a week if overnight didn't do it. I poured the used vinegar back into the jug for next time.

After 3 uses it will turn into balsamic...win-win.

Do you need to treat the item after using the Krud Kutter to prevent it from rusting again?

Anyone know if this is safe on paint? Have a bit of rust just starting to form along side my wheel wells and was wondering how this would work on cars?

I tried to find expiry information on the stuff, but didn't see any. They sell it in a 55 gallon drum, so I'd suggest it probably takes a while to expire haha!

They suggest it protects the surface for a year after, but I'd say that's a stretch and under ideal conditions inside or something. It's mainly used for removing rust from items to be painted, or from all metal items such as a wrench that can be re-sprayed etc.

From the manufacturer's website: 12. Will it hurt paint?
It is water based and contains no solvents, so it will not remove or penetrate paint. If rust is present under a coating, the coating must be removed through mechanical methods before The Must for Rust can go to work. However, if any overspray is left to dry on paint, it can both soften and discolor the paint. To prevent this, simply wipe excess remover from the painted surface after applying the product.
-------

I've personally used it during a truck restoration project on the frame, leaf springs, and other badly rusted metal components and it worked great. No leftover residue and no effect on painted surfaces/chrome/plastics.

It needs to soak for several hours to be effective doesn't it? Just applying it with a brush or something where most of it will run off won't do much I don't think.

The method shown in the Project Farm Youtube video in my original post shows a good method for how to get it to soak into a rusted area. I had great success with it
