Sorry I'm so slow to respond to your request. I didn't know this wall was here and my son had to help me figure it out. The solution I used was a water based solution that came in a clorox sized jug. Can't remember how much it cost but I don't think I have anywhere near that much invested in it. I've used it a few times and let stuff soak in it but I'm basically an old school guy and find myself using a little gasoline in a margarine tub to scrub and rinse the little things. Let me know what you wind up using and what kinda success you have. Don't know that I have the best solution figured out.
