Better than regular...
September 16, 2014
But I don't know if it's worth the premium price. I tried it vs standard SONAX wheel cleaner on opposing wheels a couple times, the first time I did no scrubbing, there was a marked difference, but neither one was good enough. Then following week I tried it in the brushless carwash, again, the PLUS side was better, but still not great. Finally I hand washed and used my brushes, both sides were identical, I probably used a little less of the PLUS just because of the sprayers, but I didn't measure.
Pros:Usual SONAX quality, works marginally better than the standard if you're in a hurry.
