Step 1: Tools Materials
Sandpaper assorted form 80-140 grit ~$5
Screwdriver with interchangeable bits (should have one very useful)
Paper Towels for cleanup of various steps
Foam Brushes ~$0.80
Parts and Materials
Coffee (you will see)
Butcher Block Conditioner ~$10
Threaded Casters ~$10 for all 4
Replacement Knobs ~$6 for 2
Step 2: Cleaning and Sanding
Once manor pieces are removed, such as the handle or the knobs on the cabinet, the sanding can begin. Sand with the grain of the wood, I sanded it by hand. Start with a rough grit such as 80 and sand down until the surface stains are gone. Progress to finer grit up to 140 to smooth the surface.
Step 3: Staining
Alternative, remember that coffee? it is good for more than just keeping you awake. A dark brew that is cooled and unfit to drink will stain unfinished wood and is infamous for leaving coffee rings on the table. Well good lets preemptively stain the entire surface.
Use the brush and keep the surface clean using the sponge/towels. Let the surface dry, it will not have the darkness that it had when wet but we will fix that.
Start with the mineral oil applying it to the wood will lock in moisture and bring out the dark color. The Butchers Block Conditioner I used is mineral oil and wax, it is messy at first so make sure you have towels to rub it in and dry off any puddles.
Step 4: Replace Hardware
Step 5: Finish
The inside is still not redone but is was sanded and cleaned.
Storage improvement like baskets and improved shelves
Contact paper would be a start to protect the shelves.
