Last week I ordered a qt of ONR from Autogeek. Today when I went out to my car I found it full of bird crap. I mixed up a bucket ONR and washed my car . I was very impressed with how it works. It cut the bird crap with no effored at all and in 15 minutes I had a clean and shinny car. It also seems to leave the paint , glass, and trim with a extra gloss, making a qd unnecessary. I like it.
