I usually soak it in hot/warm water for about 30 minutes and then just use a washcloth or something to try and get it out a little at a time and if that doesn't work I soak it in hot soapy water and try it that way. I think the soapy water would do better for you. It usually works for me.
I hope this helps in some way.
It is not okay. Unless the artist learned about the culture but if they don’t they are doing cultural appropriation. It definitely matters what race is involved a white artist can’t do a Chicana (Mexican culture) music. Even if credit is given they should respect the culture
