I've been thinking about buying a pesticide sprayer just for the sole purpose of pre-soaking the car with a stronger QD strength ONR and then followed by a normal ONR wash. The problem I have with this though is it defeats the time-saving purpose of ONR.
Is it just me or is anyone else having trouble with removing bird bombs and/or pollen with a properly diluted ONR wash? Recently, I was disappointed with how many spots of pollen were left on the car because the ONR wash solution couldn't handle it. The next week I came back and did a conventional wash with Duragloss CWC and it just did a way better job of cleaning what was stuck to the paint, all without having to use barely any pressure or scrubbing.
Don't get me wrong, ONR has a place in my detailing product arsenal, but being that I live in mild weather, I currently have no water restrictions, and the fact that most of the cars I detail are kept outdoors 24/7, I still prefer conventional washes. I don't do this for a living, but I don't see how some of the professionals are getting by with using ONLY ONR. Yes, whatever it leaves behind on the paint makes it look better than what most conventional washes will do, but it's cleaning ability is far behind that of a decent shampoo.
