Don’t use the collar to pull off your t-shirt
It is best to pull your t-shirt off with your hands crosswise from the hem over your head. This protects the collar and does not wear it out so easily.

Turn inside out before you wash
This protects the print and makes it last much longer.

Wash at max. 30° C or even better cold
There’s absolutely no reason to wash your t-shirt, hoodie, jacket etc. with hot water. Not unless you’re running a professional laundry in a hospital full of viruses and bacteria. Cold water will get your garment clean just as much as hot water does. But it’s much gentler on the fabric and also saves a lot of energy.

Hang to dry
The worst enemy of printed garments is most likely high heat. If you want to use the dryer anyway please make sure you remove your t-shirts, hoodies, jackets etc. from the dryer before they are completely dry and hang them up or lay them out to finish drying.

Iron lukewarm
Too hot ironing also helps to ruin your new favourite t-shirt. And please: Never iron the printed area!

Never bleach or dry-clean
Just like using hot water it goes with using harsh cleaning products on your t-shirts. Instead, use a stain remover for spots.

Wash together with similar clothes
Last tip from the dna merch laundry department: Wash your t-shirt, hoodie, jacket etc. with clothes that not only have a similar colour but also a similar texture. For example, washing your t-shirt together with towels is nearly as pleasant for the t-shirt as rubbing a piece of sandpaper on your skin.
