I tried one of these yesterday, for the scuffs and scratches that have accumulated on our cabinets over 23 years. I applied like a felt marker, and ran my finger over to blend. It worked great!

Matthew, I am in the process of "shining" up the interior of our 32 year young "baby". I found out that a simple application of Howard's Feed and Wax not only covers the scuffs and scratches, but it pulls out the original shine and glow of our walnut paneling. I was so impressed, that I tried it on our house kitchen cabinet doors right under the sink. Originally, I rhought I was going to have to sand them and restain them, but after an application of the feed and wax, they look brand new. Just a thought!!!!
We use "Old English." It works well for us.
