Genuine Top Tip
I used to work with a bloke who'd keep a bar of standard soap in the top of his tool-box. This was not for washing his hands.. This was for preventing the accumulation of dirt and grease under his fingernails as he worked.

Before starting the day, he'd sit and carefully scratch at the well-sorn grooves in the soap thus filling the under-fingernail-gap with solid soap.

At the end of the day's work, he'd wash his hands and wash the soap out.

His fingernails were always spotless...

Remeber that next time your'e about to scurry under the car, or to work in the garden: It works a treat, and a bar of soap with scratch marks in it is always a good conversation point.
