Howdy folks, anyone ever used this method to clean a classic cars engine and bay area before? What were the results like ? Price ? Etc ….. if so do does anyone have any decent before and after pics ? From watching some YouTube it looks impressive (I’d just be worried about old wiring) A few companies out there offering this , so anyone have any advice, experience, thoughts? Cheers in advance ! 👌
