Use a blow dryer (not too close) for water in your ear after swimming.
Water in your ears is such an annoyance after swimming.
Sometimes it comes out by shaking your head, but not always. Using a blow dryer near your ear can dry out the water that’s being stubborn.
Keep the dryer about as close as you would for hair drying and stop if it feels too hot. If all else fails, go to sleep with that ear on the pillow and hope it comes out while you sleep.
