ok, i found this nice 4x4 still invelvet and i want to let i stay like that and the hair on the outside is all gone and the velvet is still intact.But there is still some of the brain tissue stuff on the inside and it smelled pretty bad when i first found it.But it doesnt smell right at the moment because it is like 10 degrees outside.How would i get all that stuff out and get rid of the smell?
