Can I clean Rubber Stamps in the dishwasher?

No, never put stamps in the dishwasher. The combination of high heat, harsh detergent, and water pressure damages them quickly.

• Heat warps rubber and can distort the impression permanently.
• Detergents and water pressure dissolve the adhesives that hold mounted stamps together.
• Wood-mounted stamps can swell, crack, or fall apart entirely.

Hand-clean instead with lukewarm water and mild soap. It takes less time than loading a dishwasher and keeps the stamp intact.
