Quick answer

Hand wash your Stanley Reserve Wine Tumbler with mild soap and warm water to preserve its insulation and finish. Avoid the dishwasher despite its sturdy build.

Why hand washing matters for insulated barware

The double-wall vacuum insulation that keeps your wine at the ideal temp relies on an airtight seal. High dishwasher heat and harsh detergents can degrade the silicone base and lid over time, shortening the tumbler's lifespan.

The slider lid is designed to fit snugly to prevent splashes. Hand washing ensures the lid's seal stays tight and the translucent finish remains clear without clouding.

What you'll need

You don't need special tools. A soft sponge, mild dish soap, warm water, and a bottle brush for the interior are enough. Avoid abrasive scrubbers that could scratch the smooth exterior.

How to clean your Stanley Reserve Wine Tumbler

  1. Rinse immediately after use: Pour out leftover wine and rinse the tumbler with warm water. This prevents stains from setting and keeps odors at bay. Don't let wine dry inside—rinsing now saves scrubbing later.
  2. Hand wash with mild soap: Apply a drop of mild dish soap to a soft sponge and gently clean the interior, exterior, and lid. Use a bottle brush to reach the bottom of the 11 oz tumbler. Avoid abrasive pads; they can scratch the smooth exterior.
  3. Clean the lid and silicone base separately: Remove the slider lid and wash it under running water. Pay attention to the slider mechanism and the silicone base ring to remove any trapped debris. A cotton swab helps dislodge particles from the slider track.
  4. Rinse thoroughly and air dry: Rinse all parts with clean water until no soap residue remains. Place the tumbler upside down on a drying rack and leave the lid off to air dry completely. Never reassemble while wet—moisture trapped under the lid can cause mildew.
