When Costco audi told me I needed some removed & she could not do it, she told me about a drug store kit I could buy to do it myself.
I tried it several times & went back for her to look several times and it was still there (one side).
So I went to YouTube and a Dr. had a video on using hydrogen peroxide (a common medical disinfectant when diluted) as a cleaner.
One try and wax was gone. Obviously stronger than the drug store stuff but works!
YMMV so just passing this along.
