Again, GreaseMaster managed to clean the surface thoroughly without hurting it. Even though the wood was both porous and prone to absorbing moisture and even though GreaseMaster was at 400:1. I had to apply it twice with a spray bottle, once for the initial cleaning and the second time to get the spots I missed the first time. I also used a soft nylon bristled brush to scrub the grain and help break up the oils and dirt in the wood, followed by drying with a cloth and rinsing off the residue with a damp towel (to make sure the handle didn't become slippery again if it got wet while in use, I couldn't feel any residue when it was dry).
