I wore my watch in a hot tub . Now it won’t turn on or charge

What should I avoid while wearing my Apple Watch?

Water resistance isn't a permanent condition and can

diminish over time. Apple Watch can't be rechecked or resealed for

water resistance. The following can affect the water resistance of

your Apple Watch and should be avoided:

• Dropping Apple Watch or subjecting it to other impacts
• Exposing Apple Watch to soap or soapy water (for example, while showering or bathing)
• Exposing Apple Watch to perfume, solvents, detergent, acids or
• acidic foods, insect repellent, lotions, sunscreen, oil, or hair dye
• Exposing Apple Watch models other than Apple Watch Ultra to high-velocity water (for example, while water skiing)
• Wearing Apple Watch while cliff diving or high diving
• Wearing Apple Watch in a sauna or steam room above 55° C (130° F)

While the above should be avoided, if your Apple Watch comes in

contact accidentally with soaps, shampoos, conditioners,

lotions, perfumes, solvents, detergent, acids or acidic foods, insect

repellent, sunscreen, oil, hair dye, or any substance other than water,

it should be cleaned with fresh warm water and dried with a lint-free

cloth. Chemicals found in these items could negatively affect water

seals and acoustic membranes.
