Embracing the trend of self-expression and personalisation, vinyl decals have become the go-to choice for customised mugs and tumblers.

Their vibrant designs, flexibility, and impressive durability have made them a favourite among those looking to add a unique touch to their drinkware.

Here at melly, we take pride in using only premium permanent vinyl for our customised mugs and tumblers, ensuring that your designs not only look fantastic but also withstand the test of time, even in outdoor settings.

While our premium vinyl can handle the great outdoors with ease, it’s important to treat your unique melly creations with a bit of extra tender loving care when it comes to using them with dishwashers and microwave ovens.

1. Temperature Sensitivity of Vinyl

Vinyl, a type of plastic, has a temperature sensitivity that makes it vulnerable to extreme heat.

Dishwashers and microwaves generate high temperatures during their cycles, causing vinyl to degrade, warp, or peel.

This not only compromises the aesthetic appeal of your customised drinkware but may also release harmful substances into your beverages.

2. Dishwasher Agitation Effects

Dishwashers use powerful jets of water and detergents to clean dishes thoroughly.

The force and abrasiveness of these cleaning agents, combined with the agitation of the dishwasher cycle, can be harsh on vinyl decals.

Over time, the constant exposure to water and cleaning agents can cause the vinyl to lift or deteriorate, rendering the customisation less durable.

3. Microwaving Vinyl Risks

Microwaving vinyl-decorated mugs or tumblers poses another set of risks.

The intense heat generated in microwaves can cause the vinyl to melt, releasing toxic fumes and compromising the integrity of the design.

Additionally, uneven heating may result in distortion or damage to the vinyl, affecting the overall appearance of your personalised drinkware.

4. Chemical Interactions With Vinyl

Vinyl is susceptible to chemical interactions with the detergents and heat-resistant coatings used in dishwashers.

These interactions can accelerate the breakdown of the vinyl material, leading to premature wear and tear.

The combination of chemical exposure and temperature fluctuations in dishwashers can compromise the safety and longevity of the customisation.

5. Longevity of Customised Mugs and Tumblers

Customised mugs and tumblers are often cherished for their personal touch and unique designs.

However, exposing vinyl decals to the harsh conditions of dishwashers and microwaves can significantly reduce their lifespan.

To preserve the longevity of your customisation, it is recommended to opt for handwashing and gentle cleaning methods.

6. Safety Concerns

Beyond the impact on the appearance and durability of the customisation, there are safety concerns associated with using vinyl-decorated drinkware in dishwashers and microwaves.

The release of harmful substances during heating or exposure to chemicals can pose risks to your health, making it crucial to prioritize safety over convenience.

7. Handwashing as an Alternative

To ensure the longevity and safety of your personalised mugs and tumblers, handwashing is the safest and most effective method.

Begin by selecting mild detergents that promise effective cleaning without compromising the integrity of the vinyl decals.

Opt for those gentle formulas that cleanse without being overly harsh, allowing your drinkware to maintain its vibrant personality with each wash.

Avoid abrasive counterparts that might scratch or wear down the surface of the vinyl.

Instead, opt for soft sponges that provide a tender touch, ensuring your customisation remains pristine over time.


When it comes down to your personalised mugs and tumblers, it’s all about cherishing the uniqueness of each sip, relishing in the memories associated with your customised designs, and ensuring that these cherished companions remain an integral part of your daily rituals for years to come.

At melly, you know you will be getting high-quality premium vinyl for your custom mugs and tumblers.

By taking these simple precautions, you can ensure they not only retain their visual appeal but also serve as enduring symbols of your style and commitment to quality.
