I had fairly bad etching on my paint and someone on here recommended microfibre and boiling water and let it soak. It worked as I guess it draws the oils out of lacquer.A pro grade coating and ideally one that has an element of self healing so that if it does stain it then you can heat them out 90% of the time.
The thing with removing them with a microfibre is that you have a fairly big risk of scratching the car.
I actually have a belter of an etching on my wing from bird**** sitting on the car after sitting at the airport. Will put a video up of how easy it is to sort with a self healing ceramic
That can work too, depends how deep into the clear it goes. Sometimes that may look like it’s fixed the issue as it causes to the clear to swell then as it sinks again it will reappear.
Prevention is better than the cure.
Of course I thought it would never work, the fake hawk was put up on Thursday evening and zero poops on my car since, I might invest in a mini one to hang on my aerial when I'm out and about
