Apieu Squeaky Brush Washboard

It's Apieu's Squeaky Brush washboard.

If I wash the brush using only my hands, is it properly cleaned?

I bought this brush washboard because I felt uneasy about washing brushes, and it is very light and small.

I like that the brush washes well^^ I can put my fingers in, so I can clean it securely! The price is also affordable, which is great!
