Best Rust Penetrator?

[sider68]

I,m about to do some tear down and was wondering what everyone recommends to loosen rusty bolts before i break them and my knuckles. WD 40 seems to be most popular but Ive seen everything from 3 to 12 a can

a 3foot extension on the rachet works wonders// a torch is great//a spray bottle filler with vinegar(about $3 a gallon) works good// sometimes the most effective is to turn the wrenches clockwise and just snap the bolts

I've had good luck with this - especially if you can let it soak a good long time...

I am NOT a fan of WD-40 as a penetrating oil, PB Blaster is far better.

cdowns has a point though about breaking them though, as long as it's a bolt/nut situation, it works well.

p blaster is the **** !!!!!!

I read one time that GM sells the best stuff for this. The kicker is that it sells for about 8 bucks a can....

There was a big thread on this about two months ago. Let me see if I can find it.

There was a showdown of products a while back I saw on the net about penetrating oils. The winner was actually a mix of 50% acetone and 50% ATF. Worked better than PB Blaster and Aerokroil (sp?)

PB rust penetrator is the best I've seen.
Let it soak, &/or use heat before trying to break loose. With aluminum motorcycles etc. Sometimes you can just give it a "bump" in the tighten direction then snap back to loose mode.
I'm sure like everything else. You'll get it.
Used it on a lot of Vintage motorcycle restoration work, and of course my ole' 72 raised in Utah. (salt roads)
Theres also acids for large jobs but california epa took most of the good stuff.

PB gets er done, at least in my experiences. Although I will have to try that vinegar trick Cdowns.

I can vouch for the vinegar trick. I just poured 2 gallons in a bowl and put some old rust 72 parts in it for about a week. Took them out and they look new. I just washed them off and primed. Amazing.

The best is aero kroil you can get it usually at you local catapiller dealer along with the best grade bolts money can buy.Kroil is a step above anything you've ever used and won't let you down.

[Tkmadone]

I like the CRC brand of penetrating oil.

[nickp51chevy]

I'm going to try the vinegar trick.

[Beelzeburb]

I exclusively use Kroil myself, but I've only ever heard good things about PB Blaster too.

[beebster]

My dad was a big fan of "tightening" the bolt just a hair, then it would loosen. It works especially well on screw heads.
I used to be a fan of WD 40 until i got a can of PB Blaster. that stuff is amazing.
now it's all i use.

My favorite spray is In-Force from BG Products. Its expensive but it really works. It foams.
The best thing was posted earlier. Canning Wax & a Torch!!

[mbgmike]

Yeah the vinegar trick has been used for years nothing real new. Most of the chemical companies I have worked for have been mixing up their own version for years cause it cheap.

PB Blaster is pretty good, Deep Creep (I think by Seafoam) is great.

Vinegar works great for de-rusting parts, never thought of trying it for a stuck bolt. By the way, if you soak things in vinegar, you need to have some water & baking soda ready to dip the parts in the kill the acid from the vinegar, then be ready to treat the part with Rust Mort or something - the vinegar strips the metal & it will flash rust very quickly - within minutes.

WD-40 has its place like in the house for squeaky hinges but never had any luck with it on missouri rust. LOL PB Blaster has my vote it works real good. Gotta try the vinegar though, heard of it but never tried it. If GM has something in a can for $8 i would bet anything its made by someone else and sells at walmart or oreillys for $3 a can. Just like orielly brand oil I dont think they have their own refinery. LOL But hey a feller can be wrong.

I'm a fan of Liquid Wrench and a liberal, (Gee I hate that word!), dose of patience! If you can shock the bolt/nut with a hammer tap after applying Penetrant. Al W.

The next time your around a case dealership ask for industrial strength rust penetrant. part number b505501 i sell it for $3.89 its awesome. except the smell. but try it it works.

This marine shop down here on the coast sold me this stuff called corrosionX!! This stuff is unbelievable!!! I Had these trailer door hings that were sticking pretty good. used tons of stuff on it PB WD Grease oil everything. I shot it 1 TIME, let it soak for couple minutes and the door flung open and smacked the side of the fender. Now you just unlock it and let go of it and the thing flies open!! Unbelievable stuff. Its worth the 14.95 a can.

[special-K]

PB Blaster works so well and 1 can lasts so long I never think about cost.It just works.The key is juice it up and wait.It and anything else needs time to do it`s stuff.The only instant solution is shocking it (smack with a hammer straight on) and/or heat.Sometimes tightening first helps break a bolt loose,too.
