Can I Put a Wooden Cutting Board in the Dishwasher?

NO

Do not combine these. Use the alternative instead.

No, unless the manufacturer labels that exact board dishwasher-safe. If you cannot confirm that, wash it by hand with warm, soapy water and dry it promptly. Dishwasher heat, moisture, and detergent can warp or crack wood, while repeated moisture changes can stress glued joints.

The conditions

Fine to do

  • Use the dishwasher only when the maker labels that exact board dishwasher-safe.
  • Follow any rack, cycle, or drying limits in the board’s care instructions.
  • If the label or manual is missing, hand-wash with warm, soapy water and dry promptly.

Never do

  • Do not put an unapproved edge-grain or end-grain board in the dishwasher.
  • Do not machine-wash a laminated or glued-strip board unless its product instructions allow it.
  • Do not assume solid wood alone means dishwasher-safe; manufacturer directions vary.
  • Do not use a shorter cycle or switch off heated drying as a workaround for an unapproved board.
  • Do not soak the board in the sink because prolonged wetting can also warp wood and strain joints.

Why those conditions exist

  1. Moisture changes shape

    Wood absorbs water and swells. As it dries, uneven shrinkage can leave the board warped or split.

  2. Glue lines take stress

    Glued strips and blocks do not move exactly like the adhesive between them. Moisture cycling creates stress along the bond, which can weaken it or open a seam.

  3. Surface protection degrades

    Dishwasher heat and detergent can damage the board’s protective oil or finish. That leaves less protection against later moisture.

Conflicting Advice

Broad guidance and product instructions do not line up perfectly. USDA says some solid-wood boards can be washed in a dishwasher while warning that laminated boards may crack or split. Major cutting-board and dishwasher manufacturers often tell owners to hand-wash wood.

Use the care instructions for the exact board. Solid wood does not tell you whether its finish, construction, or glued joints were designed for a dishwasher cycle. With no clear dishwasher-safe label, keep it out.
