I've been on the hunt for a good tweed jacket for a couple months here in OKC and I think I've found it!
My question is can one successfully wash a thrifted tweed jacket without jacking the thing up? I was planning to lay flat it in the tub, spray it with cold water from the shower head, put a small amount of woolite in, squish and mash it for a few minutes, drain the dirty water, rinse til the water runs clear, rolling it gently to push out excess water, and hang on a coat hanger with a fan blowing on it. As often as I'll be donning this jacket, I wanted to start off with one that was not thrift store grimy.
Have you considered having it dry cleaned?
