Deskmats from my shop are typically 90 x 40 cm and are a full-bleed, threaded-edge sublimation print with super bright colors! That being said, they can still be machine washed should you get any stains on them or if you need to freshen them up 🙂
It’s not easy to see but my food cube desk mat had a bit of water stains from cups and generally needed to be freshened up.
I used a top-loader washing machine with only a small amount of detergent on tap cold and regular spin cycle settings.
I loaded the washer only with the desk mat but it would probably be fine washed with other clothing that either has no dye or has been washed before. Clothing with dye that has never been machine washed might bleed onto the printed surface.
It also went through the dryer on a medium heat with no issues! I would recommend drying the desk mat either by itself or hang drying it as the non-slip back of the mat may get covered in lint due to clinging.
But yeah! These are perfectly washer and dryer safe and it is recommended to freshen your desk mats every month or so depending on how often you use your PC/desk.
