Dome-shaped roofed structures
built to house sacred Buddhist items of worship are called<span> studpas. They are built to hold Buddha’s
ashes and other sacred items. Sometimes they are bell in shape. Guests may
visit around the studpas to pay their respects to Buddha.</span>
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.
Definitely Bob Ross looks like something he’d do
