Saw the TW trim restorer on the shelf at my local WalMart. It was cheap enough at $7 to try. Previously I used Mothers Back To Black. Initially it looked good but over 4 weeks has started to fade a bit. I grabbed a cheap MF and applied this thickish liquid on it and rubbed it on textured black trim. The towel turned black, really black, so this stuff seems to have really good cleaning ability. The towel went in the trash when finished.

It left a dark wet look on trim. Not sure how long this will last but at this point, it seems to be a winner.
