If you want your vocal mixes to sound clean and pleasant, then you need to use deesser plugins.

Deesser works with sibilance and helps to reduce harsh sounds produced by letters such as S, T, F, C, etc.

It’s the main tool for mixing vocals but it can be used for different instruments such as cymbals, hi-hats, and even guitars.
