Sublimation printing has revolutionized how we customize everyday items like mugs.
With vibrant, full-wrap designs that really make mugs pop, it’s no wonder sublimation products have exploded in popularity.
But under the surface of those stunning prints are important questions around safety and care.
Can I microwave my favorite sublimated mug? Is it okay to scrub it clean or pop it in the dishwasher? Will the ink wash off over time? Is it even food-safe?
If you’ve found yourself wondering about the do’s and don’ts of using sublimation mugs, this guide tackles all the key questions.

Are Sublimation Mugs Microwave Safe?
If you are wondering “can you put a sublimated mug in microwave”?
The answer is yes, most quality sublimation mugs are specifically manufactured to be durable in microwaves when used properly.
Sublimation mugs are often made of ceramic, which is microwave-safe
The coatings and inks used are also rated for high temperatures, as they permanently bond to mug materials using heat infusion in the sublimation process.
However, it’s still smart to verify microwave safety rather than assume, especially for cheaper mugs.
Always check labels and packaging for explicit safety wording before microwaving any mug for the first time.
Phrases like “Microwave Safe”, “Oven and Microwave Safe”, or “High Temperature Resistant” help confirm proper safety testing was completed by the manufacturer.
If uncertain about microwave durability, try this simple test before first use:
What exactly is the microwave risk?
Essentially overheating any mug material, coating or ink to the point of breakdown.
Ceramics could crack, coatings bubble and peel, plastics warp. Inexpensive mugs often skimp on durability testing and use lower-grade materials prone to microwave failure.
But well-made sublimation mugs use robust, microwave-compatible materials that simply heat up without issue.
By taking some simple precautions to verify microwave safety first, sublimation mug owners can confidently continue enjoying their favorite drinks piping hot anytime.
Are Sublimation Mugs Dishwasher & Food Safe
Beyond microwave compatibility, understanding dishwasher durability and food safety is critical for daily, regular use of sublimation mugs.
No one wants to risk damaged prints or dangerous chemicals leaching into their favorite drinks.
So can sublimation mugs go in the dishwasher?
The good news is sublimation mugs are generally durable enough for dishwasher cleaning.
Their ceramic, glass or thick plastic materials can withstand hot water, friction and detergents during wash cycles without structural damage or delamination issues.
Can you put sublimation mugs in the dishwasher? well this is what a user on this Reddit thread said about dishwasher safety for sublimation mugs:
However, for the longevity of printed mug designs, handwashing is still best practice, which we’ll cover more in the care section.
Sublimation mugs are also food-safe, since sublimation ink/polymer coatings use safe, non-toxic materials approved for dishware. So feel confident enjoying your morning coffee or tea without worries.
The specialized polymer coatings and sublimation inks used must meet regulations for product safety, using non-toxic materials that won’t leach even with repeated heating and washing.
So while surprising tastes or chemical leaching risks are extremely minimal with properly made sublimation mugs, their safety for direct food/drink contact is also mandated for legal sale in most regions.
Reputable vendors stand behind their safety certifications.
Still, it can be confusing to navigate the standards around these customized products. Let’s explore some pro tips on safely cleaning and caring for sublimation mugs long-term next.
How Do You Care For Sublimation Mugs? (4 Tips)
Proper care is crucial for keeping sublimation designs vibrant and lasting for years to come. Here are 4 top tips:
1. Avoid High Heat During Washing
While the materials and tightly bonded inks can resist heat in general household use and microwaves, high-temperature dishwasher cycles still speed up fading over time. Opt for gentle or eco dishwasher settings if machine washing.
2. Prefer Handwashing Instead of Dishwashing
Even gentle dishwasher settings subject mugs to heat, steam, harsh detergents and friction – risks absent with handwashing.
Wiping gently with soft sponges and mild detergents helps sublimation mugs maintain their specialized coatings and brilliant prints much longer.
3. Avoid Abrasive Materials
Repeated scouring with brushes or scratchy sponge pads also wears down the polymer coating on sublimation mugs more quickly, causing printed designs beneath to fade or flake earlier than they should.
While gentle wiping is fine during hand washing, avoid anything too abrasive.
4. Handle With Care
Like any drinkware, avoid dropping sublimation mugs or exposing them to temperature extremes.
Careful handling maintains both the structure of the mug itself plus that crucial polymer coating protecting the custom print.
Consider hand washing or drying to lower risks of cracks, chips and scratches over time.
FAQ on Are Sublimation Mugs Safety
For new users of sublimation mugs, questions around safety, ink durability and unexpected issues often come up. Here’s answers to some of the most common queries:
1. Does sublimation wash off mugs?
When properly made, sublimation ink infuses tightly into polymer coatings on mugs using heat and pressure.
This bonds the ink permanently at a molecular level. So no, sublimation designs don’t simply wash off or fade quickly from occasional cleaning when care guidelines are followed.
However, frequent hot dishwasher cycles plus detergent and friction can accelerate fading and wear over time if coatings break down. And overly-abrasive scrubbing with brushes may eventually damage prints. For longest lasting designs, gentle handwashing is best.
2. Why does my sublimation mug look faded?
As highlighted above, repeated or excessive heat, detergent chemicals, friction and abrasion from scrubbing are the enemies of sublimation mug coatings and prints.
Fading issues typically result from too much exposure to one or more of those risk factors.
Consider mitigating future fading by switching a heat-damaged mug to handwashing only. Always use soft sponges and gentle wipe-cleaning instead of abrasive scrubbing.
3. Why is my sublimation mug bleeding?
Ink “bleeding” on a new sublimation mug usually indicates the ink didn’t fully cure and adhere permanently to the polymer coating before first use.
When washing new mugs, inks can then run or rub off, transferring unwanted inky residue onto hands or in water.
Mug bleeding is due to rushed or deficient heat-pressing during the sublimation process.
On quality mugs, sufficient temperature and pressure permanently drive inks deep into durable coatings.
Always buy sublimation products from reputable sellers following safety protocols, and ensure proper curing at home if making DIY sublimation blanks. Properly treated mugs won’t bleed or fade.
4. How do you stop sublimation mugs from ghosting?
Ghosting on a sublimation mug refers to faded “shadows” of a design remaining visible after the polymer coating itself begins wearing away. It’s typically seen on older, heavily-used mugs.
Aside from switching to more gentle handwashing methods, ghosting itself can’t be reversed once coatings degrade. But it can be prevented by avoiding excessive handling and washing cycles past the mug manufacturer’s longevity estimate.
If buying cheaper sublimation blanks marketed as “one-time use novelty items”, the lifespan may be under 50 washes. Invest in quality blanks rated for 300+ cycles from reputable vendors, and replace mugs once coatings show substantial wear.
Conclusion
When manufactured properly by companies adhering to product safety standards, sublimation mugs rate quite safe for normal household use including microwaving, dishwashing, and direct food/drink contact.
Still, following care best-practices helps mug owners preserve the longevity of these customizable products even further.
