thanks to sifu
KrisMas i totally found the holy grail of wheel cleaner:
basically sonax wheel cleaner and/or megs WB combo (atm i'm using TW until i can get my hands on megs)
1) just the sonax alone, spray product (i spray a lot, basically almost finished KrisMas febreeze in just 2 front wheels, rear drums anyways)
2) leave on 30sec - 1min +/-
3) water down (slightly high pressure)
VOILA CLEAN NO NEED SCRUBBING LOL
i then proceed to spray some TW wheel cleaner (http://www.turtlewax.com/detail-F21%20Wheel%20Cleaner-44-117.aspx) just to further wash off sonax and whatever else that sonax loosened up (but isn't meant to clean, kinda complicated and it took a while for krismas to explain it to me haha) and yeah, i finally get what everyone meant by sonax wheel cleaner's smell LOL
anyways after i did a second water down for the TW wheel cleaner (obviously did this for the rear wheels as well haha), i did a minor test by poking in my finger to the rotors, did a few rubs on the surface and guess what...

MY FINGER IS CLEAN!!!
i totally and absolutely no longer need to use the wheel brush anymore! effectively cut down
AT LEAST 20-30 minutes on scrubbing all 4 wheels!
now... where can i get more of that product? need a gallon or something keeping stock
oh and what should i do with the wheel brush

It's very expensive and you need to have deep pockets to use it every wash! Just do a proper cleaning of your wheels and then seal it up with a sealant or wax. Subsequent washes will only need shampoo and minor agitation.
IMO, no matter how strong or good the wheel cleaner is, some agitation is still required to leave a spotless surface.
