How should I wash/care for my MKSG Brand rashguards?

We instruct care/usage on the inside label of each rashguard.

Please wash cold, inside and out (to reduce friction and potential damage from other articles of clothing). We do not recommend washing any rashguards with clothing that contains velcro- velcro hooks onto clothing within proximity and has a tendency to ruin the design, fabric, and threading. Yet another reason we admonish washing inside out!
