My Experience With Free All Vs PB Blaster

I grabbed Free All and PB Blaster in May 2025, tired of snapping bolts on my old truck’s exhaust system after a salty winter.
On May 10, I sprayed Free All on a seized lug nut, letting it sit for 20 minutes while I sipped coffee.
The nut turned with a satisfying creak using my wrench—impressive for a product I’d never tried.
PB Blaster came next on May 12, tackling a rusted brake caliper bolt.
Its sharp smell hit me first, but after 15 minutes, the bolt gave way with less torque than I expected, though I coughed a bit in my garage.
June 5 brought a humid day, and I tested both on my mower’s blade bolts.
Free All soaked in smoothly, loosening the rust with a light spray, though I reapplied after an hour for a stubborn one. PB Blaster cut through faster, leaving a slick residue that protected the metal, but the fumes lingered, making me crack a window.
On June 20, during a rainy fix, Free All’s no-silicone formula kept my painted parts safe, while PB Blaster’s strong action risked a slight discoloration I had to scrub off.
July 1 tested them on a trailer hitch pin—Free All needed a second dose, but PB Blaster’s deeper penetration won out after 30 minutes.
Now, at 12:06 PM +06 on July 07, 2025, after 58 days, I’ve used both on nuts, bolts, and hinges across my projects. Free All feels gentler and versatile, while PB Blaster packs a punch for tough jobs. You’ll see how they stack up depending on your needs, so let’s dig into the details from my garage battles.
