Quick post - DIY'ers who suffer from rusted/stuck bolts

[bmninada]

3 days worth of PB Blaster and Benzomatic, etc. was used to release few bolts on my 2016 Mazda 3 weeks ago.

Met a guy who works in Newark Airport and he suggested I instead try

Kroil Original Penetrating Oil​

Boy oh boy - this thing really works. My passenger side was worse and I was putting it off. Just on a whim sprayed with Kroil and today attempted to take out the bolts. Boom - little pressure and off it came.

In home I have something which is stuck for ages now. Tried there. Took 2 times but worked.

Its pretty expensive compared to PB Blaster but it works.

Kroil is great not always easy to find. My local muffler shop gave me good trick that really works take a torch heat up the bolt /nut and wick in candle wax

Kroil is good stuff… I’ve been using it since the early 1990s.

Amazon has it = the whole shebang....

Isn't the fastest, in my experience. But if there's time to let the Kroil soak (say, over days) ahead of a project, it's great. Have used it on many stuck nuts and bolts.

FML, ~$50 for a 10oz can in Canada... I find its always best to use preventative measures where possible. Fluid Film every 6 months if you live in a rust best. And anti-seize on every bolt you touch.

Crayons work great too.

The company I used to work for bought Kroil in 55 gallon drums… I always wondered what the price was for that. Must’ve been a lot, cause a few years before I retired they switched to "Knock'er Loose".
