Just getting started in Houston. So far I am brush washing homes and using a trailer mounted 4000PSI/4GPM (CAT 66DX with 18HP Honda) pressure washer with GP 22" surface cleaner for ground surfaces and also using machine for rinsing various surfaces. I want to use less elbow grease (brushing) and utilize the softwash process. I understand the difference between the two is nothing more than amount of pressure at surface being cleaned.
My question is this: If using my pressure washer to soft wash, do I simply strengthen solution since I will only be collecting 20%-25% of solution using downstream method? I have found several solution ratios for low pressure pumps but nothing regarding using pressure washer. I would imagine that the cleaning solution would be diluted far to much with down streaming therefore I would need a stronger solution. Thanks in advance.
