Caring for Your Glass Tumbler

Caring for Your Molly's Glass Tumbler

Your tumbler has been made and finished by hand, so a little extra care goes a long way in keeping it looking beautiful. Below you'll find everything you need to know about washing, storing, and handling your glass.

🧼 Washing Your Tumbler

We recommend hand-washing your tumbler in warm (not boiling) water with a mild washing-up liquid. Use a soft cloth or a long bottle brush to reach the base of the glass.

  • Avoid harsh scouring pads or abrasive cleaners — these can scratch or dull the glass surface.
  • Rinse thoroughly and allow to air-dry upside down on a clean drying rack.
  • Do not soak for extended periods, as prolonged soaking can affect seals and finished surfaces.

🍽️ Dishwasher Use

We do not currently recommend placing your tumbler in the dishwasher. The high heat, harsh detergents, and water pressure used in dishwashers can affect hand-applied finishes, painted designs, and any adhesive seals on lids. We are reviewing dishwasher safety for our range — please check back for updates, or get in touch if you have a specific question about your tumbler.

🪄 Lid Care

Your tumbler lid is designed to create a snug, leak-resistant seal. To keep it working well:

  • Hand-wash the lid separately with warm, soapy water.
  • Remove any silicone seal or gasket where possible and wash it individually.
  • Allow the lid and gasket to dry completely before reassembling — trapped moisture can cause odours over time.
  • Do not twist or force the lid; a gentle press-and-turn is all that's needed.

🧃 Straw Care

If your tumbler came with a reusable straw:

  • Clean after every use with the straw cleaning brush provided, or a small pipe cleaner.
  • Rinse thoroughly with warm water and allow to air-dry fully before storing.
  • Glass or metal straws may be cleaned with boiling water; check the material of your straw before doing so.
  • Replace your straw if you notice any cracks, chips, or damage.

🎨 Hand-Finished & Painted Surfaces

Many of our tumblers feature hand-applied designs, decals, or painted motifs. These finishes are applied with care and pride — here's how to protect them:

  • Avoid rubbing painted or decorated areas with abrasive cloths or scrubbing pads.
  • Do not use nail varnish remover, acetone, or strong solvents near decorated surfaces.
  • Some light fading may occur over time with regular use — this is normal for hand-finished items and adds to their handmade character.
  • Handle with care when stacking or storing to avoid chips to decorative areas.

📦 Storage

  • Store your tumbler upright on a stable, flat surface.
  • If stacking is necessary, place a soft cloth or piece of kitchen roll between tumblers to prevent scratches.
  • Keep away from the edges of shelves or worktops, particularly in busy kitchens.
  • Store lids and straws separately, fully dry, to prevent mould or odour build-up.

🫶 Handling Tips

  • Glass is naturally more fragile than plastic or metal — take care when handling on hard surfaces.
  • Avoid sudden temperature changes (e.g. pouring boiling liquid into a cold glass). Allow the glass to reach room temperature first.
  • Check for chips or cracks before each use. A damaged glass should not be used for drinking.
