How to test products for abrasiveness

What kind of tests can I do to compare the abrasiveness / cleaning power of common products, like for example how can I tell if a cleaner has mild abrasives or it's just chemicals?



Any ideas?
 
Use old CD's (compact discs) as a sample surface. They are very sensitive to scratching and gives obvious results. Scratch one way with as uniform pressure as possible using a foam applicator or finger.
 
Yep, what Brad said. That's the standard used by many autopians here. Myself included (although I'm still a newbie). Just be sure to use CDs you no longer need or just grab one of those AOL 9.0 Optimized disks you got in the mail (come on, admit it. You were stockpiling those disks for years hoping for a use for them!) :D

This means:



I make one pass on a new CD with either the foam applicator or the finger with product. If it scratches it has abrasives, or



I scratch the CD and then see if I can remove it with the product?

(just to be sure what you mean).



What about the cleaners, and the products that may have enough PD to remove what was there, is that a test we can do with a marker pen and see if the product removes the ink?

Make a couple passes with your finger or foam applicator and see how little or how much it scratches. Use the same amount of pressure, product, same # of passes etc.

Hmm, I thought the "CD scratch test" was for testing if a buffing cloth or drying towel would scratch a surface...



So it can be used to test a product as well? Guess I learn something new everyday. :cool:
 
Well, to have a compare term I used DACP and after 20 sec. rubbing it with my finger I had only micro scratches. None with P21S GEPC (supposed to have light abrasives) nor with my test subject, 1Z's Wax Polish, a great polymer based wax supposed to polish! ... Didn't leave any mark on the CD. :nixweiss

I can't say that I've used it myself, but a friend of mine does it to compare products before applying to his paint. Seems to work for him. I just read about them online first (yeah, I can be lazy)

I guess the CD test shows that DACP is much more aggressive than GEPC and 1Z Wax Polish. (I already knew that! hehe) Just kidding.
