This is no less than the NASA experts advice on how to make your printed tees and jumpers last longer (on Mars... sure).
Given that over half of the carbon footprint in the lifecycle of a tee is produced by our use of the washing machine, iron and tumble dryer, there is a lot that we can do also about that (while still on Earth).
Wash them inside out
If you are taking one piece of advice, this is the one. You will wash more effectively the bits where your body rubs all day long, while protecting the prints at the same time.
Sort out your life and washing
This is to preserve colours and excessive friction on the fabrics: wash your tees together, similar colours and materials, avoid mixing them with zippers and buttons. Of course, everyone knows not to overload the washing machine.
No long and hot sessions
How many times did you wear the shirt, once or twice? A quick cycle will work most of the time, saving up to 30% of water and up to 60% electricity compared to a full and never ending cycle.
Dry it out in the shade, avoid the tumble dryer
It will save nearly a quarter of your t-shirt's lifecycle carbon footprint and your heart from breaking after quickly spoiling your favourite t-shirts.
Ironing… don’t iron it!
But if you really have to, don’t do it like it’s landing on Mars: iron inside out on low temperature and, if you can, use a cloth in between the iron and the garment.
Keep your t-shirts in shape, not just yourself
Bonus tip from Mars: don’t hang your tees (“no wire hangers” Mommie Dearest said) and fold them instead. Finally, don’t pull them from the neck when taking them off! All this will prevent them from looking deformed and out of shape.
This landing on Mars was already a real cornucopia of discoveries for us.
