A travel cup being dishwasher safe depends on the material it is made of. Generally, travel mugs are dishwasher safe but the ones which have textures outside sometimes start to wear off because of the hot water of the dishwasher. All travel mugs can be washed with hands.

The capability of a travel mug to without the temperature whether it is cold or hot depends mainly on the insulation used. The more the insulation, the more the ability of the travel mug to withhold temperature, but it also increases the weight, which is not a desirable quality in a travel mug.

There are mainly three types of travel mugs:
• Stainless steel: This type of travel is the most common, their body is made up of stainless steel with different insulation like single, double, and triple wall.
• Plastic: This type of travel mug is made entirely of plastic, both body and insulation, they are very lightweight but temperature holding capacity is lower in comparison.
• Ceramic: This type of travel mug was used in the initial period; they are on the heavier side and breaks easily. Also, the ceramic starts to show leakage after long use.

Yes, travel mugs are made keeping in mind that most of us would be in a car. Generally, the travel mugs are made of standard size at the bottom to fit perfectly into your car’s cup holder.

Well, it may not sound like it but there is a difference between spill proof and leak proof. A spill-proof travel mug will not spill over when turned upside down or sideways. And a leak-proof travel mug would not leak upon any jerks or because of its design flaws. Any escape liquid will also not be sprayed on you upon opening the lid.
