Choosing “Raw Unfinished” or “Clear Matte” means embracing the full character of steel—color shifts, visible textures, scratches, and the marks left by the hands that shaped it.

Keep your new merch looking killer! For light cleaning, gently wipe wood shelves using a soft moist cloth and warm water, then dry immediately. For additional care and protection we recommend Howard Wood care products to clean, polish and condition.

Step 1

If using a mild cleaner, dilute it in a warm bucket of water

Step 2

Immerse a clean microfiber cloth into the bucket then wring it out

Step 3

Gently wipe surface clean

Step 4

Repeat steps as needed

Larger orders? No problem. We’ll still get you the best available rate—including LTL freight for anything over 124 lbs or over 84-inches long. Rates are calculated in real time based on your order’s size, weight, and destination.
