Cleaning fuel/oil residue from my hands has always been a problem.
Try using a shot of hand sanitizer by Dial or Purell or such. No more greasy hands. This wonderful stuff. No rinsing-just rub it around and maybe dry off- like on a towel or someone elses shirt!
You’re going about this all wrong.
Ditch the engines and the noise.
Green soap and glycerine, that’s the way.
Easy on, easy off with just a light mist of water.
Use your own shirt or someone else’s.
Rubber, all the fun , all the frustration, without the noise and mess.
