The previous best insect, I bought

My fast standard procedure is: Auto (car is fixed) to the car wash.
I spray the area with a the insect remover, then clean with a high pressure cleaner the side sills, wheels, etc., and finally then the treated sites. The reaction time is then so 3-5 minutes.
So then you get problems from approximately 95% of the insects impacts. The rest will be done the carwash. After the washing, remain only minimal insect residues. In any case, the best ever result cleaning. When hand wash it works basically the same way.

Have the cleaner has often used and can no problems on paint, plastic or metal parts (incl. Aluminum and chrome) notice. He is also quite economical. The spray head dispersed.

I am very happy with it and would recommend it unreservedly.
