What Customers Are Saying

Customers overwhelmingly praise this penetrating oil for exceptional rust-breaking performance, consistently freeing seized bolts and frozen fasteners where competitors fail, with many reporting dramatic results within minutes and calling it their go-to lubricant. However, a significant concern undermines satisfaction: many users report spray cans losing pressure prematurely, leaving product unusable when half full, even on new cans. Some mention strong odor and flimsy spray mechanisms. Despite packaging frustrations, most customers consider the liquid itself highly effective and worth repurchasing.

Would Recommend

Life Saver: Grandfather Clock Family Hierloom

Would Recommend

Hurricane Sally devastated the Gulf Coast of Florida, specifically Pensacola, where I live. I am building a new office/studio and a week prior to the Hurricane, workers brought my 130" wide granite desktop through the dual front doors. They inadvertently left the left front door deadbolts (this door secures both doors with its vertical up & down slider pins) unlatched. At 5:30am Sally's 95mph winds blew both front doors open breaking a flower pot in my foyer and saturating my 96" tall 100th An...

Best penetrating oil ever

Would Recommend

Have used this for years, very pleased will buy more. Recently had a malfunction with a can so I emailed them. Company quickly replaced the can. The customer service is awesome! They even sent stickers that look great on the shop tool boxes!

Good Product but No Pressure

Would Recommend

This stuff does work, but like others have noted, you get down to the bottom third or quarter of the can and - pfffft - no pressure left. What I've done (an old farmer trick) is to punch a small hole in the bottom side of the can with a nail and let the remaining fluid drain into a clean container until the can is empty, then pour the leftover PB Blaster into a trigger sprayer bottle - one with a sprayer head that has both a stream and a wide setting - and at least then you're not throwing a st...

The best bar none

Would Recommend

I have decades of experience in mechanical and maintenance jobs, this is the best product in the industry.

Disappointed!!

Would Not Recommend

I tried to use it on five (5) rusted screws on my gas grill. I tried several times, along with leaving the product on for a lengthy amount time, but could not get them to budge! Probably my fault, the direction for use mentioned nuts & bolts but not "Screws"! Lesson Learned! I guess I'll keep it around in case I have any rusted "Nuts & Bolts".

Use this in my freezer, stinks up food

Would Recommend

I had rust building up on the metal parts in my bottom freezer. I sprayed a little to get the drawer to pull out smoother, but the smell now stays in the refrigerator. I thawed it out and clean it. No smell. Turn it on and next few hours, you smell it again. How can I fix this?

Shoo-wee!!!

Would Not Recommend

I'm not going to say that this product doesn't work, it probably works quite well. The problem is, it should only be used on an industrial level & definitely not for residential use. I bought a can of this to spray on a squeaky truck door before taking my wife on a nice drive & My God! The smell was so horrifically strong that we had to just try and get home. I personally find this product to be dangerous. I will go back to WD-40 and throw this can in the trash. By the way, not only did it ruin...

Used on hopelessly rusted shocks on Jeep. Treated em everyday for five dayts--they cam out like they'd just gone in. The key is patience and letting this stuff work.

Overwhelming smell makes this product useless!

Would Not Recommend

A family member recommended this for a heavy sliding glass door that was becoming increasingly harder to open. He sprayed some along the bottom where the wheels are. It fixed the problem, but the smell made me feel nauseous. I spent the whole night with a headache that wouldn't go away, even after taking medication that usually takes it away immediately. I looked up reviews this morning to see if I was the only one experiencing this. One review mentioned the smell and that he later learned t...

Amazing Product!

Would Recommend

I work on small engines, and i couldnt get a bolt out. I ran to Lowes later that day and saw this and bought it. Sprayed it on and not five minutes later the bolt was completely free. 10/10 would (and will!) definitely buy again!!!

Disaster

Would Not Recommend

My mechanic carefully sprayed a little down the slot in my passenger side window and wiped it immediately. A full week later with windows open the chemical small is still so strong I can't drive my car without getting sick and now have to wear a face mask just to drive it. Product should come with a warning to NEVER EVER use it in an enclosed space. Your product has rendered a perfectly fine and carefully maintained vehicle useless.
