In this video, I’m doing some simple preventive maintenance on my BMW Z4 convertible and showing you a new product that actually makes sense for interior work: PB B’laster Clear & Low Odor Penetrating Oil. Convertible tops, sunroofs, and interior pivots all have moving joints that dry out, bind up, and start squeaking—especially on cars like the Z4 where the top can stick mid-cycle. The big deal here is this formula is low-odor, so you’re not stuck smelling penetrating oil in the cabin, and it sprays on clear so you’re not risking orange stains on trim, carpet, or light-colored surfaces. I walk through where I like to use it: convertible top linkages, seat tracks (especially manual tracks that get gunked up), door hinges and door check straps, and even clutch and brake pedal pivots up under the dash. The can has a flexible hose you can bend to hit tight spots, a trigger lock, and an adjustable tip so you can switch between mist and spray—and you can close it so it won’t drip when it’s stored. Another bonus is it doesn’t have silicone in it, so it’s safer to use around paint work as long as you wipe it off. If you’ve got squeaks, sticking parts, or dry pivot points inside your vehicle, this is an easy way to keep everything moving smooth.
