i use a 60/40 mix of sodium hypoclorite 12.5% with 1/2 cup of tsp per gallon and occasionally a good soap when needed for a surfactant

I use a 30-40% mix of SH. Works great! 60% is a bit hot for asphalt shingles...just not needed down here, and more likely to burn plants.

i realized after talking with don that you may be getting a fresher batch of chems than i am because it is used so much more frequently in florida and at that rate you could mix it weaker and get the same results

Check with your supplier and find out how often they get a fresh batch in. Chlorine doesn't degrade as fast as some folks think it does, especially if it is kept in a dark tank. The place I get it from has a 2000 gallon black tank, and gets refilled at least weekly.

That's cheap.
It's $2.15 a gallon here for 12%.

$116 for a 55 gal drum here plus tax. And no delivery.

russ s · 07-12-2006, 11:54 AM

is that with a drum deposit added?my price is w/o a drum deposit ...its a one time fee anyhow i just got back from ordering 110 gallons

Thad · 07-12-2006, 12:38 PM

$118 plus a $40 drum deposit here.

$2.50/Gal here for 16%. They think I'm wierd because I am the only PW'er here using it. The Local PW stores here don't even carry stainlees tips or the higher oriffices. I have to order online to get good tips. Stuff like this tells me that there aren't many guys here that know how to adjust pressure or shoot chem. The Local suppliers look at me like I am retarded when I ask for a #0030 tip.

Thank Goodness for boards like these. You'll notice I don't post a whole lot, but I am constantly reading. Like someone here said. 2 eyes, 2 ears, 1 mouth. I guess I learn more by reading than posting.

My wife gets a kick out of it when I start laughing when you guys do goofy stuff or a "here's your sign" post is read and or responded to.

I usually buy between 100 and 150 gallons at a time, that's good for anywhere from 2-5 days before I need a refill.

Yes, most of that is roofs. If I'm doing mostly houses or flatwork that week, I may go through 50-75 gallons, depends.

russ s · 07-13-2006, 08:14 AM

i tend to use a lot more when doing roofs but like we talked about earlier i use more chem in my mix than you do

Reef Pressure Washing · 07-20-2006, 08:22 PM

We are currently paying 0.99 per gallon. It is delivered daily ( I think ) and there are 3 or 4 1,500 gallon tanks.

We are pretty slow here.
We have went to a 50/50 with some TSP. the TSP depends on the house.

russ s · 07-20-2006, 09:54 PM

wow thats a great price

Of course, buying that much at one time has its drawbacks...If you have a full tank and things slow down as they have the past three weeks, you wind up with a tank of WEAK chlorine...Sprayed 80 gallons on a roof today and will have to come back Tuesday and re-spray any areas that haven't faded out or rinsed off in the rain by then. The house was so bad I just gave up and told the customer I'd be back Tuesday.

Why Tuesday and not today? I have a leak in my tank, and need to fix that Monday, which will be a several-hour task...ripping the plumbing all loose, replacing the fitting on the tank, and re-plumbing everything. Have a large concrete job tomorrow or I'd fix it then. Anyway....chlorine definitely weakens too much after three weeks! It was about 1/3 10.5% and 2/3 water to start with. What a waste!

russ s · 07-28-2006, 01:58 PM

i have noticed that too
