pre show foam wash would you pay??

[Rob.c]

Guys

I have started a mobile car cleaning business in my spare time,

I had the thought of offering a pre show ph neutral foam and rinse to help get the cars clean, from my experiene i have seen plenty of people washing their cars either on stand or at any available tap.

Would you pay for a £5 foam and rinse to help with car cleaning???

Any positive comments are welcomed

Thanks
Rob
