We have the same routine. I throw it in the wash and air dry after. I made the mistake of using fabric conditioner and threw it in the hot dryer before when I didn’t know better. Thankfully, my Gi didn’t exhibit any signs of damage.
My biggest problem was that smell that came from dried up sweat and moisture from the mat and something else and it drove me really crazy! I experimented on different detergents but there was still a faint scent on it. Call me fussy but I really wanted my Gi to look and smell fresh every single time.
I recently discovered Tide Pods and so far I’m very satisfied. I’m not sure though if overtime it’s going to ruin my Gi since I’m not so familiar with its chemical composition.
