Howard Feed and Wax. Hands down the best thing for wood and even leather that has a worn finish. Rub plenty on, rub it in, let it sit for 30 minutes or so, then wipe off the residue. I use that along with Howard Restore-a-finish on all my antique pieces. I use them together a couple times a year and it will extend the life of the wood significantly.
We have a 25 year old sofa and chair that have been our main sitting pieces the whole time. I’ve been using the Feed and Wax for several yearss. Without it, we would have had to spend a couple thousand dollars to replace the leather. We also have a small antique leather side chair that was in not great shape when we got it, but between Restore a Finish and the wax on the frame and the wax on the leather seat, it looks absolutely gorgeous.
Have you noticed a change in color after putting it on?
Yes. As with anything that “wets” wood, it will darken it temporarily. Our front door is fir. It was stained, but never varnished. It faces southwest and gets the full brunt of sun and weather the whole year. I give it a good dose of Feed ‘n’ Wax a couple times a year and it keeps the wood from drying out and the door looking like new.
