Valve Stem cleaning?

I tried to clean my valve stems with Googone and a tooth brush, and not very happy with the results.
This car is only 6 months old, the wheels look brand new except for the valve stems.:shead:
Thanks

 

Valve stems on the wheels? You should be agitating them with a wheel brush and the wheel cleaner while doing the rest of the wheels.

 

New ones are cheap, and then you have a fresh start on maintaining them :thumb:

 

Huh? Every 6 months? Porsche valve stems cheap? Remove wheel and tire to replace?:shakehead:

 

Spray some APC or wheel cleaner and agitate with said toothbrush, cuts grease, brake dust, debris.

 

Yeah some APC or wheel/tire cleaner and a toothbrush should do the trick. Also, you could apply some type of rubber dressing to help maintain them.

 

are they tpms or just standard valve stems (ie rubber) that makes a world of difference............

 

They are gonna be TPMS, he mentioned in the initial post that the car is only 6 months old.
