Quick Answer

Wash your Marvel Tumbler by hand with warm, soapy water and a soft sponge. Avoid the dishwasher and harsh scrubbers to protect the finish and insulation.

Why Hand Washing Is Best

The Marvel Tumbler's triple insulation and sliding lid are designed for everyday use, but the dishwasher's high heat and strong detergents can gradually break down the seal and affect performance. Hand washing is gentler and keeps the cup looking its best.

If you're short on time, a quick rinse after each use prevents residue from building up. This makes the weekly deep clean much easier.

What to Avoid

Avoid abrasive scrubbers, steel wool, and bleach-based cleaners. They can scratch the finish and dull the Marvel design. Also, never soak the tumbler for long periods, as water can get trapped under the lid or in the insulation layer.

The lid is shatterproof, but it's still best to handle it gently. A soft brush can reach the sliding mechanism without causing damage.

Step-by-Step Cleaning Guide

  1. Rinse Immediately After Use: Empty the tumbler and rinse with warm water to remove leftover drinks. This prevents stains and odors from setting in. A quick rinse saves time later and reduces the need for heavy scrubbing.
  2. Hand Wash with Mild Soap: Fill the tumbler with warm water and a few drops of dish soap. Use a soft sponge or bottle brush to clean the inside and outside. Pay attention to the rim and threads. Avoid abrasive scrubbers that can scratch the surface.
  3. Clean the Sliding Lid Separately: Remove the lid and wash it with the same soapy water. Use a small brush or cotton swab to clean the sliding mechanism and the seal area. A clean lid ensures a tight seal and prevents leaks.
  4. Rinse Thoroughly: Rinse all parts with clean, warm water to remove every trace of soap. Leftover soap can affect the taste of your next drink. Taste test with plain water if you're unsure—any soapy taste means you need another rinse.
  5. Dry Completely Before Storing: Shake off excess water and place the tumbler and lid upside down on a drying rack. Let them air dry completely before putting the lid back on or storing. Storing a damp tumbler can cause odors and mildew.
