I was using some Griot`s Heavy Duty Wheel Cleaner today, and I noticed I wasn`t getting any color change. At first I didn`t think too much of it, I never seem to get much color change, perhaps from ceramic brake pads, etc. Then it dawned on me that it was 35 degrees outside (with snow flurries) and that it may be the reaction is significantly slowed (longer than I was willing to wait given the temperature). Has anyone else noticed this? It makes sense from a chemistry standpoint.
