What do you suggest instead of a sponge? I have to be careful as the alloys are painted and i don't want to scratch them.
I threw the sponge away years ago. They hold grit over time and can act like fine sandpaper. I use the Meg's lambs wool mits as they are super soft and if you rinse then between panels (two bucket wash) , you can get most of the dirt and grime out, thus less dirt going back onto the car etc.
I have two Meg's lambs wool mits. One for the paint work and one for the wheels (note: the mit for the wheels started out washing the car but as it aged, it became the wheel cleaner).
No matter how you wash your car, you will get some level of scratching, but how you wash your pride and joy, can minimise such. Remember, long lateral wash strokes, i.e. back and forward the length of the panel, not round and round. Any micro scratches will be harder to see as a result.
I have the same issue re lack of shade, thus it's always a late arvo car wash for me.
