Our cabinets are the "Colonial" style units - I think some might call this "Pecan". We're only 2 adults and take care of the kitchen (in particular) wiping up etc., but, after a while the units did look "used". I tried a few things, including, the dealer, Heartland, and custom cabinet makers- not one could match exactly or could furnish a small can of touch-up liquid (call it stain). BUT,lol, thanks to my brother-in-law, I was able to refinish and touch up marks, nicks, and weared spots. The remedy? SHOEPOLISH!!!
and it not only covers up but being a wax, it does a fair job of sealing. The way to do it is a clean dry cloth, apply on the affected area, and with ANOTHER clean cloth, lightly rub the applied section. It works fine for me and I hope anyone looking to improve the looks of their cabinets will fell the same way. BTW, in my case, I used a "Dark Brown" shoe polish, not a liquid, but the small round tin. Good Luck.
