Cuban Mechanic Reveals Genius WD-40 Tricks Dealers Don’t Want You to Know

Most car owners have no idea that a six dollar can sitting in their garage right now takes care of jobs that shops charge $200 to $500 for. Today I’m going through 18 WD-40 tricks that dealers and mechanics quietly hope never get out. And don’t skip ahead, because the one at number one has saved drivers from a repair bill that can pass $1,500, and it takes about ten minutes the night before your next oil change. I’m Rafael, a Cuban mechanic in Miami. In Havana we mixed our own penetrating oil from kerosene and old motor oil in a coffee can. You’ve got something better, and it costs six dollars. In this video: The exhaust tip trick that does a $50 detail job in one minute The squeak that sends people straight to the service desk, and the ten-second fix The seized caps that stall roadside tire changes for hours A trunk that won’t latch, and why nothing is actually broken The after-the-storm trick that clears a misfire and a check engine light Protecting a trailer hitch at the boat ramp (salt water eats everything) Washer nozzles, crayon stains, a stuck fuel door, a creaking brake pedal The math the shop never says out loud The bolts under your car in salt air, bug guts and scuffs on paint, a stuck seat track, a seized jack Battery terminals in the humidity, and the customer who got jump-started four times on a good battery The wiper pivots that can leave you blind in a downpour Engine bay plastic, brought back for pennies Number one: the night-before oil change habit that saves you from a $1,500 mistake And my honest word on what NEVER to spray Not a miracle in a can. It cleans, it loosens, and it pushes water off metal. Know what it’s for and what it isn’t, and it saves you a fortune. Tell me in the comments which trick you’re trying first. Whichever one gets the most comments gets the full deep dive next. I read every one.
