Without even bothering to rinse the GreaseMaster off, you can see a drastic difference in this photograph when compared to the one above. I applied it at 400:1 for this. Although I haven't tried it, I imagine the higher the concentration level, the harder it is to wipe streak-free. I know the higher the concentration level the more foaming will occur when agitating.
