dear arhum bhai
nothing much differnce between poet and car detailer , both thirsty for appreciation for their poetry
all you u brother's appreciation injected fresh blood into me 
jazakallah for liking
if tyers/rims are rain dirty than no other choice to open tyer nuts and take off wheel covers and wash rims ( in honda city vtec u have to remove tyer nuts to take off wheel covers ) but if tyers/rims routine dirty than car shampoo solution and detailing brushes to clean wash wheel arches. for tyers frankly i use desi soap and usual brush bought from hyper star , good thing in desi soap many fats , oils so dont dry the rubber while surf make them dry and thirsty so absorb more tyer gel and protectant 
yes u can also use apc for cleaning wheel arches with detailing brushes
