How to clean stack stone?

[hyderdo 14]

I have 2 customers I pressure washed their houses last year and they called me to pressure wash the front entrance of their subdivision. They told me they had it pressure washed twice once with pressure and once with bleach! What should I use.

They both are on the Home Owners board and if I can clean the front entrance they want me to clean the curbs in the subdivision and I would be the only pressure washer on their vender list!Please help!!!!

Is it real?.. some them accents these days are made of who knows what..

I've had good success on similar (rock beds) with about 6% and no pressure.
