Vinegar WILL increase the risk of jacking up the paint. Personally, the only time I ever used it, was on the Chrome Bumper of my 96 F-150 (not on plastic "chrome") to remove bugs like no bug and tar remover can. For chrome, there is nothing better, just be careful when hosing off.. Vinegar and paint mixing, is a huge tempest in a teapot waiting to happen and I will never use it on our 2010 and 2015 MKZ's.
Someone mentioned using a California Water Blade. Maybe on the windows, but having used one about seven years ago? Too many issues can arise from the use of it on paint. I now use microfiber.
Not so much criticizing as I am trying to prevent some from potentially causing damage.
