The reason you might *think* it does is because:
* Hot water softens the polish: Heat makes the polymers in nail polish more flexible and less rigid. This can make the polish feel like it's peeling off easier when you're soaking your nails in hot water.
* Hot water helps with removal: Hot water is often used in conjunction with acetone-based nail polish remover, which is the actual solvent that breaks down the polish. The heat helps the remover work more effectively.
* Other factors: If you're doing something like washing dishes, the combination of hot water and physical scrubbing with a sponge can make it *appear* like the polish is coming off with the water alone.
To summarize: Hot water alone won't remove clear nail polish. It's the combination of heat, the chemicals in remover, and potentially physical scrubbing that makes it seem like the polish is dissolving with the water.
