Getting into more commercial accounts and larger areas on concrete, i decided to get a dual wand lance (36" w molded GRI frok power wash store), as my cousin sugessted before he made impossible to get ahold of now. So i have come here to ask what tips work great? Do u screw in a soap tip and use a standard tip for rinsing and getting into tight areas my surface cleaner cant reach? I appreacuate any siggestions and feed back. Thanks. Have a great weekend.

What does a dual lance wand have to do with flatwork? Just curious. To answer one of your questions. You use the appropriate soap and pressure tip for your machine. I have one, I think I used it once. Just use a ball valve and switch to a gun/wand, instead of carrying an extra doodad.
Also. Using a dual wand means you keep your injector inline. On flatwork, you either need an injector bypass or you remove your injector(to be efficient and smart)
[MENTION=7766]RalphQ[/MENTION]. I was watching some vidoes poeple using a dual lance/dump gun, you turn knob to let chemical out at low pressure, and close knob to rinse at high power, all withough having to walk back to truck to turn injectir off. Seems kind of efficient. But havent tried it yet. I have a couple drive thru lanes this weekend to do. I currently have a cold water unit still, hot water is on its way. Just trying to get a feel for the dual lance before i use it or leave it at shop. I understand about having to carry extra crap you dont need. I also hear some people would rather use dual lance in tight corners. I dont understand that, as a regular lance with turbo nozzle wild do it… Or am i wrong there, cause it worked for me in past.
By efficient you mean easier on you, right? To be efficient, you would want every bit of flow your machine can provide. Having an injector inline, robs you of valuable flow. Rinsing power is the most valuable asset you have for flatwork. If you just soaped up an area, walking back to the truck=dwell time. I don’t do commercial concrete, but I do a LOT of residential driveways. I got my cut in and wand work down to a very small %, just using my surface cleaner.
Dual Lance wands are mainly for fleet washing because of the repeated soap/rinse cycles. Unless you’re not using a surface cleaner and still wanding an entire driveway…then, well we’re not talking about efficiency at that point. Otherwise use a regular Lance with a 4-way/jrod to select your rinse or soap nozzles.
Yup, I bought a dual wand by someones advice before I had a good grasp of what I’m doing and It’s sitting at the shop, I’ve got a wand that’s about 26 inches total length with a jrod on the end, been using it for the last month and have zero complaints.
Efficient meaning less time on job. Im new to concrete, as i had to sign contracts with banks in order to keep their windows. I had cold water unit, and did plenty if driveways, and someone told me to get dual lance to spray chem and go back to where i started to spray off chem as apparently the soaps would do all the work for concrete. I just found out yesterday that soaps and chems help break some stuff up, but you still need to really clean. So i learned my lesson, ha. I injected chems, let dwell 10 mins, rinse, found out its still kinda dirty, and had to get my surface cleaner so i wasted time and effort doing an unnecessary rinse. I think i will stick to basics; spray chems, 10 min dwell, clean w surface cleaner, clean up and move on. Lesson learned. I do appreciate everyone that took time to inform me their experiences.
Dual lance wands are very useful for wood restoration. Carry two different sizes in the truck and use them on every job.
Its great idea Navarro.
