Convinced myself WD-40 fixed everything until a seized lawnmower bolt at my dad's place proved me wrong
My dad's been telling me for years that WD-40 is a penetrating oil. I never believed him, thought it was just multi-purpose magic. Last Saturday, I was trying to loosen a 15-year-old rusted bolt on his riding mower deck, sprayed it on, waited 10 minutes, and it didn't budge at all. He handed me a $6 can of PB Blaster from his shelf, I let it sit for 20 minutes, and that bolt came out with one turn of the socket. Now I keep both in my truck, but only use the PB for stuck metal parts. Has anyone else found a specific brand that works way better than WD-40 for certain repairs?
