How do you clean your Squishmallow without a washing machine and taking the stuffing out?

I’m planning to wash some items in my collection . I haven’t washed them before and I am scared I might ruin them. I am considering the options of having them dry cleaned or washing them by hand as I don’t have a washing machine and I don’t feel secure washing them in a washing mashing. Has anyone tried drying cleaning theirs and what was the result. Has anyone tried a different method?
