for shampoo can try head and shoulder, follow me, ginvera,
johnsons & johnsons....ah! mabbe lux super rich.... used by the
actors...
just trying to cheer pple up a bit...
anyway, after you have polished your car, some pple use a sealant
to "seal" the gloss, liddat the glossy look can last longer. so if
you have done that, subsequently you just need to hose the car with
clean water without shampoo. save money and effort. still need
shampoo occassionally though.
