For months now I have heard several of you talk about abrasive free polishes/waxes. As if a mild abrasive or cleaner is bad.
Often times a light cleaner is neccessary to remove dirt or water spots that do get on and in between even the best products. By using a mild cleaning agent you can safely remove light contaminants. On the other hand if you have no cleaners at all you may have to use too much presure on your towel to try and remove these contaminants which may cause scratches.
I am a big fan of Zaino Products myself. On the two white cars I test it on though I find some dirt will not come out of the paint even after washing and using Z6. By having a mild cleaner in a product you can remove this dirt without using much presure. Removing this dirt increses shine. Just because I don't see this light dirt on other colors doesn't mean it's not there. I would much rather remove this light contamination instead of sealing it in with another layer of polymer.
If your car never sees rain or the outdoors you may be fine using a 100% cleaner free product. But for the majority of us, using a product that has a small amount of cleaners is not only easier to use but safer as well.
Just because you proclaim I will never use that product doesn't mean that the products you do use are better. Every product I use I try on a cd first to see if it scratches. Finish First may have cleaners in their polish but it doesn't scratch. Beyond that on the four cars I have done side by side test on, it beads after 3 months exactly as Zaino does. Most importantly it has a Carnuba like shine which I like.
