The base cabinets in my kitchen lost their luster from years of wear and getting wet. As a renter I didn't think there was anything I could do so I've been living with them like this for the five years I've been in my place.
On a whim one day last week I decided to try wiping the cabinets with some Old English Scratch Cover.... and OMG the result was awesome:
This project only took five minutes:
Step 1 - Squirt some Old English Scratch Cover on a rag.
Step 2 - Rub the rag on your cabinets.
Step 3 - Step back and admire how much better your cabinets now look.
Step 4 - Kick yourself for not doing this five years ago when you first moved in.
