Things you have learned in life that cuts time and makes things easier.

[Andre]

Cuttlefish used with water (not the shell) cleans anything off smooth surfaces like old rusty knives, burnt cooking pots,cuts down resin fast to an even surface.Cleans glass, polished granite and marble very fast. Slightly abrasive like a powdered cleaner but doesnt scratch once you peel the shell of it.

Only rule you ever need:

Work smarter, not harder.
