If you are doing your drive way, or exterior of your house for that matter, use the liquid pool chlorine instead of regular bleach. Pool chlorine is 4X stronger than house bleach. Just be careful with your Lovelys flowers.
For house wash, in a 5 gal. bucket, mix 1 cup of liquid Tide to 1 gal of bleach or pool chlorine if you really want it bright and clean, fill the rest with water.
You can also add some liquid dish washing detergent (NOT DAWN!)Dawn makes it dangerous like WW1 chemical warfare dangerous.
The key is to allow the chemical to do the work.
Spray the solution through the pump using the black orifice, if the pump has a dema valve (venturi) pickup.
Allow it to sit for 30 mins. then using the PWs 45* fan, begin the power washing process, working from the bottom up. Bottom up keeps from washing the solution off.
1200 psi is an excellent working pressure (although it's really GPM that does the work). It allows for plenty of power should you need to get up close for stubborn spots.
