B'laster 16-PB Penetrating Catalyst - 11-Ounces

I replaced the factory front suspension on my Mustang and came across some nuts and bolts that were not only a bit corroded but were factory tight. This product really helped freeing up those nuts and bolts. Spray it on and let it penetrate. Works pretty good

Works well. good product.

Very good and effective for removing old bolts. For very difficult bolts, I spray the bolt in the morning when the engine is cold, again in the afternoon, and again at night. In many cases the bolt is easy to remove on the following morning. Of course, depending on the age of the bolt, and how fused it is with rust, there is always the risk of breaking the head. This is why I make sure it's saturated before using the wrench. So far it's working good, much better than any other penetrating oil that I've tried.

I've used this product for years working on old cars with rustly bolts. A few minutes soaking in this stuff, and 99% of the bolts come right off without issues. Wouldn't do a project without it. Price online is a little high, for you can get it at any local car parts place for less.

I was stranded on a used motorcycle in Florida about 10 years ago. It had begun to rain so hard I was forced off the freeway. At a roadside rest area, I waited for the rain to subside so I could leave. Got back on the bike and put it into first gear and it would hardly roll. Front brakes had seized! Called a tow truck and when he arrived he was clearly unprepared to tow a motorcycle. In the meantime, I called my brother (who owns a repair shop in Idaho) and talked to him about it. He said that if I could get my hands on some PB Blaster I might be able to free up the brake pistons. I asked to tow driver if he'd ever heard of it and he said "sure, got some right here in the truck!". Well, I bought that can from him for $5 and it was half full. I was able to repair the brakes in the parking lot using PB Blaster and they stayed fixed. Brought the can home to Idaho and 10 years later it ran out. So, I'm getting another can and I'll never be without this product again. It has un-seized many a rusty bolt, and is great as a cable lubricant as well. Much better than WD-40.

I burned half a can of WD-40 trying to bust bolts off my car's exhaust. This stuff did in 2 hours what WD-40 failed to do in 32 hours...SHAKE THE CAN BEFORE USE. Apply on and around rusty bolt. Then let it sit for about two hours and take it on with a long wrench.I found if the bolt is still tough, spray more and come back in an hour and try again. Got nearly every bolt off (minus one stuck in a tough spot to wrench anyways)

PB Blaster is an excellent penetrating oil and lubricant for almost any mechanical need that doesn't involve open flame or extremely high temperatures. It should also be used in a well-ventilated area. It is derived from naphtha which is created during the initial refining of crude oil so it is a hydrocarbon, like gasoline, natural gas, etc. and should be treated with similar respect and caution. If you read the Material safety data sheet (MSDS), you will find warnings about potential for respiratory and skin complications and even brain damage from prolonged exposure. Hey, it's a petroleum based solvent, what do you expect?Used properly, I think it's the best overall solvent/lubricant available, certainly more effective as a penetrating oil and long term lube than WD-40 and Tri-Flow, in my opinion ( stress "my OPINION").Any solvent, oil, lubricant, aerosol that is petroleum based should be used with caution. Water is a solvent too and it can be dangerous if you hold your head in a bucket full of it for a prolonged period of time!I use it on hinges, locks, window cranks, gun parts, faucet handles, anything that squeaks and is made of metal. I also spray it on my rotary push mower blades after each use to keep the blades sharp and healthy. I spray it on garden hose couplings, scissors, squeaky wheels and even my nose hair trimmer. If it wasn't unhealthy to digest, I would spray some on my cat to stop his constant meowing when I'm trying to take a nap. When used indoors, I make sure the room is well ventilated and have a fan going or a window open if possible.You don't need much! A LITTLE spray will be plenty on most projects if given time to penetrate.Since like substances tend to emulsify each other, it can be used to clean heavier oils and I like to use it to clean carbon deposits off of firearms; it's a lot safer than carbon tetrachloride and I think it's almost as effective. Again, MY OPINION.One last warning: If you are blind - I am totally blind - take care not to store it in the kitchen as the can is similar enough to PAM food spray that I actually once sprayed PAM on a door hinge before my son decided to tell dad what he was doing. As of yet, to the best of my knowledge, I have not used PB Blaster while scrambling eggs. I don't have any sense of smell either so even if you're as blind as I am, you should normally be able to smell the difference between PAM and PB Blaster. And before I get comments: yes I know that I could just put a simple raised label on the can to identify it, but that would make things too easy and I like the daily challenge, it keeps me alert.

This product works like magic. I had a rusted metal bolt that has probably been on my toilet since the 60's. I needed to replace it and I or anybody else could get it to budge. So of coarse I googled how to get it off and it recommended this stuff. I bought it, sprayed it on, and within a 1/2 an hour the bolt was off!Highly recommend
