Tumbler Care Guide

Tumbler Care Guide

Your Blaisie tumbler is handcrafted with a stainless steel body and a custom resin finish (some designs also include foil elements). Treating it with a little care will keep it looking beautiful for years to come. Please read the guidance below before use.

🧼 Washing

Hand wash only. Use warm (not hot) water and a small amount of mild washing-up liquid. Rinse thoroughly and dry immediately with a soft cloth.

  • Do not place your tumbler in a dishwasher — the heat, steam, and harsh detergents will damage the resin coating and any foil elements.
  • Avoid abrasive sponges or scouring pads, which can scratch and dull the finish.
  • Do not soak the tumbler for extended periods.

For the interior, use a bottle brush with mild soap and warm water to clean thoroughly.

🌡️ Heat & Temperature

The stainless steel body is double-wall insulated and designed to keep drinks hot or cold — but the exterior resin coating is not rated for high external heat. Please follow these precautions:

  • Do not place the tumbler on a hob, in a microwave, or in an oven.
  • Do not leave it in direct sunlight for prolonged periods (e.g., on a car dashboard or window sill) as UV exposure and heat can cause the resin to yellow or lose gloss over time.
  • Do not place the tumbler directly in a freezer.
  • Avoid resting the tumbler on surfaces that are very hot (e.g., radiators, hot plates).

Hot beverages such as coffee and tea are fine inside the tumbler — the insulation keeps external temperatures manageable.

🎨 Protecting the Artwork & Resin Finish

The custom artwork is encapsulated beneath a clear resin coat. To keep it vibrant:

  • Avoid knocking or dropping the tumbler — impacts can chip or crack the resin.
  • Do not use alcohol-based cleaners, acetone, or solvent sprays on the exterior, as these can cloud or lift the resin.
  • Store your tumbler away from sharp objects that could scratch the surface.
  • If your tumbler features foil elements, be especially gentle — foil can be more sensitive to abrasion than standard resin finishes.

🧃 Lids & Straws

Lids and straws (where included) can be washed by hand in warm soapy water. Remove the lid seal/gasket periodically and clean it separately to prevent build-up.

  • Do not put lids or straws in the dishwasher.
  • Allow all parts to air-dry fully before reassembling to prevent moisture build-up.

⚠️ Important Notes

  • [CONFIRM WITH BLAISIE] The resin used on our tumblers is intended for the exterior only. The interior of the tumbler is uncoated stainless steel. Please confirm whether your resin or finishing materials carry any food-contact certification before making food-safety claims here.
  • These tumblers are intended for personal use by adults. Keep out of reach of young children.
  • If you notice any chips, cracks, or peeling in the resin, discontinue use and contact us.

Looking after your tumbler correctly means the artwork stays vivid and the finish stays smooth. Got a question? Get in touch — we're happy to help.
