Hahaha

you funny man. Just I get second van Ford E350, brand new Hydrotek, electric titan hose reel, gray hose. What ever need another extra stuff... When I was saying "I don't have a budget for soft wash." I was thinking about $25k - $30k, truck tank equipments. Really I don't like it cheap stuff, they are not working at all, I learn from my experience. I was looking more info about Xjet, or more easy and effective systems/methods.
Please let me know guys if there is a any good chemical mix and x-jet. And thank you all, I'm reading all answer and I will try them.
Pressure washers are for pressure washing, not roof cleaning.
The X Jet will not work well for roof cleaning, you need a dedicated roof cleaning pump. I care not how much money you spent, the truth will set you free, but you may not want to hear it.
If I spent 25 to 30 K for a cleaning rig, and the guy I bought it from did not equip me for roof cleaning, after I spent all that money, I would be very upset!
It is possible to clean roofs with a pressure washer using a downstream injector. However, you need a very small GPM Machine (like 1 to 2 GPM)
My old friend Jeff LeCours "The Condo King" did it.
However, it is very very messy!
The problem with downstream injection is the draw rate is very low, this means the amount (ratio) of the liquid chlorine to water will be very weak.
So, to compensate, we try to increase the draw rate by using a very small GPM Machine.
Jeff LeCours used a 200 dollar Home Depot 2 gpm pressure washer, just for downstreaming roofs.
Trust me, a higher GPM machine will not work at all!
So, unless you already have a very small GPM machine, you are better off buying a dedicated roof cleaning pump.
Any Questions ?
