“My sublimation mug lost its print after one wash!”
If you’ve ever sold or used sublimation kitchenware—like mugs, plates, coasters—you may have heard this frustrating complaint. But here’s the truth: not all sublimation blanks are dishwasher-safe. The issue isn’t with sublimation itself, but with the coating quality and material compatibility.
So, which sublimation products are safe for the dishwasher? And how can you ensure your beautiful designs don’t fade after a few cycles?
Let’s break it down clearly.
Understanding the Dishwasher Dilemma!
Dishwashers expose products to:
- High temperature water (65–75°C / 149–167°F)
- Strong water pressure and detergent
- Long cycle times (up to 1 hour or more)
These factors can damage poor-quality coatings, dull colors, or cause edge lifting if the blank isn’t made for dishwashing. That’s why product material, coating type, and print quality all matter.
✅ Generally Dishwasher-Safe Sublimation Products
1. Sublimation Ceramic Mugs (AAA or AAA+ coating)
- If marked as “dishwasher-safe” or “AAA+ grade”
- Coating can withstand up to 350+ washes
- Ideal for home use, cafes, corporate gifts
2. Sublimation Stainless Steel Tumblers / Bottles
- Double-wall insulated types with high-temp resistant coating
- May be top-rack dishwasher safe (check manufacturer’s guide)
- Recommended: Air dry immediately after washing
3. Sublimation Glass Cutting Boards (Tempered Glass)
- With sublimation coating on the underside
- Durable under high temperatures and pressure
- Ideal for home kitchens, restaurants, souvenir shops
4. Sublimation Enamel Mugs (High-quality, non-rust)
- Enamel + steel core versions often safe in top rack
- Avoid harsh detergents to protect the rim coating
5. Sublimation Glass Coasters (Tempered Glass)
- With image printed underneath
- Scratch and heat-resistant
- Easy to clean and sanitize
⚠️ Hand Wash Recommended Products
6. Sublimation Aluminum Bottles / Flasks
- Coating is less durable under hot water and detergent
- Prolong image lifespan with gentle sponge washing
7. Sublimation MDF Coasters / Placemats / Trays
- Paper or fiberboard core swells in dishwasher
- Clean with damp cloth only
8. Sublimation PU or Canvas Aprons / Oven Mitts
- Fabric sublimation is usually washable, but not suitable for high-heat machine washing
- Spot clean or gentle cycle only

And if you’re a seller or gift shop owner, add a care instruction card or sticker to your products — it builds customer trust and prevents returns.
