And thanks to them, I not only avoid extra waste, I also save money because I don't have to buy water on the road anymore. In the meantime there is a huge offer of coffee mugs to go and drinking bottles made of different materials (some more beautiful than others – a bit hard for an aesthete like me not to put on all of them right away). But to make sure there are no nasty surprises lurking in your drinking vessels, here are my top tips on how to clean your coffee to go mug, thermal mug, or water bottle.

As eco-friendly as reusable water bottles and coffee mugs to go can be, so can cleaning them: Use a biodegradable dishwashing detergent based on plant-based ingredients, such as Sieving Generations Dishwashing Detergent Free& Clear makes it easy.

Special cleaning tablets or denture cleaner

Some suppliers of drinking bottles and coffee mugs to go offer special cleaning tablets to rid them of musty smells or stubborn residues.

Special case: cleaning thermo mugs

If you like your coffee nice and hot and your water nice and cold, you probably use insulated containers. If you want to clean your iso bottle or thermo mug, you have to keep in mind that they are not allowed in the dishwasher under any circumstances. On the one hand, water can get into the gaps and mold away, and on the other hand, the insulating effect can be impaired. However, baking soda or denture cleaner are safe when cleaning the thermo cup and for daily cleaning you can simply wash them with detergent and water.
