Caring for your mug
Washing your mug
Mugs that do not have gold accents are technically dishwasher safe, however I recommend hand washing to preserve the life of your mug.
I recommend gently hand washing mugs that have gold accents or decals (like the ultrasound mug). These things can be removed from the mug with vigorous scrubbing.
Microwaving your mug
Mugs that have gold accents are NOT microwave safe. I use a 22k gold luster, which is a metal. Metal + Microwave = Explosion!
Mugs that do not have gold luster added are microwave safe.
