For mugs, we recommend hand-wash only to ensure the print lasts as long as possible. Mugs are safe for microwave use, but do not leave a mug in a microwave for more than 5 minutes.
Shirts/hoodies should be turned inside out, washed in cold water and tumble dried on low to ensure longevity of both print and fabric. If you are worried about shrinking, then line-dry apparel. Ironing is not recommended, as some print methods (plastisol) are heat cured and will melt.
We do not recommend washing posters or CDs.
