A couple weeks ago, I brought my car to a detailer. At the time, I asked the detailer to clean out some black marks that were on the white paint door surfaces on my car. I saw him use a pink bleach like substance with a cloth to clean that out.
However, I also noticed that this cleaning substance left some residue behind and I think this is what is seen on the photos below.
Would you know if that is the case and about how I can address the residue shown on the photos below?
