Used to use Carplan shampoo.
Need to use a lot to get foam.
i heard>> car shampoo with more foam is good for car washing as it reduce friction and get rid of dirt easily.
personally, I find it quite true... I use Armourall wash (blue colour)>> the foam not a lot so i always see dirt on the car after shampooing.
hmm then end up also roughly the same as other brands?
Carplan >>need to use alot to get foam but cheaper
Other good brands (Duragloss, Meg, Autoglym,etc)>> use a little to get foam but expensive....
BACk to square one again.. NO such thing as cheap and good leh..
