Bleach is not an acid even though it is a corrosive, look at the ph of Bleach, it is near the high end of the ph scale where acids are on the bottom of the ph scale.
Sorry guys. My bad. I think it was around 3am when I posted that and I had been talking about bleach and housewash (not to mention a whole lot of other chemicals) and how to neutralize bleach's effects with my supplier a few days before and got confused with another chemical "Sodium Thio Sulfate" (I think that's how you spell it) that does neutralize bleach. Sometimes we talk about so many things I get confused. Sorry about that. I will double check my replies from now on.
Just like Christopher said, it's not "acidic". I just get the "corrosive" aspects of bleach in my brain and my hands type faster than my brain sometimes. My apologies. As you can see by how much I write, I love pressure washing as much as I do learning and sharing info about it and man, when I get on a rant - look out. As you can tell, I'm a gearbox man!
Thanks Christopher for the correction and for keepin' me straight. Whoo-wee! Talk about embarrassing if that ever got out on the internet!
Hey BlueBiss, you're ok. Sorry dude, didn't mean to scare you there. I should have stated that the housewash "dilutes" it. And even though it dilutes it, the right housewash will also "kick" it up a notch so that you don't need to use as much bleach. I only use 1 to 2 gallons of bleach to 3 or 4 gallons of water in a 5 gallon bucket and about 8 ounces of housewash concentrate depending on how bad the mold is.
Sorry about getting you guys off equipment.
Oh, and OffDutyFireman, I have indeed had packings last 3 or 4 years or more back when I did this part time. I now do this 7 days a week and run my machine anywhere from 6 to 10 hour a day. Even though I use a 5 to 10 micron filter (depending on what's in stock), they still wear out. Sometimes when I clean boat docks and have to suck water from the lake, this tends to do a number on the packings too. Plus, through the years, I've had "helpers" that didn't pay attention and ran the tanks and pumps dry - with a 5.6 gallon pump, sometimes a house faucet doesn't always keep up with the pump. Especially if you run both a 5.6 and a 4 gpm pump from the same tank on the same house. So, last year was my last year hiring "helpers". I work alone now except for a groundman when I do chemical cleaning on roofs, so we'll see how long they last now. I always carry extra packings and replace them myself. It only takes about 30 minutes, which is faster than the time it takes me to drive to my local repair shop and I'm back to work before you know it. I keep a tight schedule, so I can't afford to lose much time. Same with carbs, solenoids and injection valves. I built a twin engine trailer for a guy a couple of years back and because he hardly used the machines (he was just starting out) after about 6 months, he began having starting problems so he took it to local shop where they promptly charged him $400 for "carburetor work". The carb was only $85 brand new and only takes 15 minutes to replace - at least, that's what I would have done.
Here's a tip for everybody: For the last couple of weeks my chemical injection valves totally quit working on me. After about 3 days of messing with them, I finally gave in and took it to two different shops and even they couldn't figure it out. One sold me a new injector valve and said I'd have to throttle my engine down to about half way for it to work - I didn't understand that since I've never had to do that before. It did work, but it would barely reach two story soffits. Another sold me a new gun and 100' of new hose, suggesting that maybe I had a "collapsing" hose or a gun that wasn't opening up all the way. Heck, I even bought a new cutoff valve - and nothing worked. Now, I've known these guys for years and know they wouldn't intentionally rip me off. Altogether, I bought 3 new injector valves from 3 different suppliers and none of them would work (Envirospec, Powerkleen Corp and Northern Tool). I was at my wit's end. (Before this happened, I had no problem getting chemical through 450 of hose when I cleaned boat docks) Then the other day, while I was waiting for my tank to fill up at a job, I decided to take the injectors apart and noticed that even though all the injector valves came pre-assembled with quick connects,
none of the injector valves had thread sealer on them where the quick connects attach to the body of the injector! So I wrapped some teflon tape around them, put them back together and presto! Man, I had chemical coming out of there like gang busters! I couldn't believe it! Two weeks of agony because the manufacturers were too cheap to use teflon tape (or thread sealer)!!! You just don't know how happy I am to have my injectors working again. Even my wife noticed a change in my attitude. Heck, I even took her down the Helzberg's jewelry and bought her a necklace and earrings! What a difference a chemical injector can make. For the last couple of weeks, I had to use a 12 volt sprayer to apply chemicals. (A pump-up sprayer just doesn't cut it on a 5,000 sq. ft. two story home with a two story birdcage.) And man, what a drag it is dealing with more than one hose. So, there you go folks. Don't say I never you nuthin'! Merry Christmas!
Well, I gotta go. The phone's ringing off the hook and I've already got a half dozen estimates I've got to get out today. Shoot, I'm booked through January and working on February. Everybody have good one and be safe out there! Over and out!
