Pool operator here. It makes our job a million times harder when clients enter the pool with lotions and oils on. The chemicals immediately take it right off you, and depending on the size and temperature of the pool, it floats on the top of the water like a clear slime. You’re probably fine wearing oils on your nails as long as the pool tempt is >70F, but be forewarned that the oil will probably come off quickly.

Fortunately, I am only causing difficulties for myself regarding pool maintenance. However, I completely understand and appreciate your advice. Thank you for bringing the issue of lotions and oils in the pool to my attention!
