Orin Buddhist ritual bell

Purchased 3 years ago.
It was kept in a Buddhist altar.
The bell has been lightly wiped, but the dirt shown in the images remains.
It might come off if washed with water and scrubbed vigorously... but it will be sold as is.
The base of the bell is clean and in good condition, I believe.
The mallet for the bell is also in good condition, I believe. This is subjective, so please refrain from purchasing if you are concerned.
