Grimy Wood Handle
Here's a hammer that's been around a while and has a pretty nasty handle. Between dirt and body oils from handling it over at least 20 years, this hammer makes a great test for GreaseMaster on wood. Click image to enlarge.
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).
