Apparently the halfords mitt is for polishing only, is this correct?
Bilt hamber auto wheel - used on cakes front wheels and agitation was required before and after. Probably wasn't helped by the fact that they need a refurb.
On the lightly soiled rear wheels it was another story though, as they worked a treat. I'd still say agitation is required.
To combat this in future though I could utilise a wheel sealant and regular cleaning.
As for the wool mitt it's not the smoothest action, but definitely soft and holds a lot of water.
One thing that came out on top was sonax bsd as even after a month, it helped clear all dirt with a rinse and leaves the car smooth after washing. I was tempted to apply some more but thought nah I'll leave it till next time to really test its longetivity.
