    PDQ 4000 still a good machine?

    They're fairly simple to work on. Parts are still readily available. None of the new touchless machines can produce a better car, they just offer more show. A couple of things to think about would be what version chip are inside the A-5000's mounted to the doors of J0 and how much is it to...

    After thoughts from the 2019 Nashville Car Wash Show

    I use to go to the show every 3 or 4 years and was always amazed at the new stuff on display. Now I go every year and it seems like there are only a couple of new things to see each year, but I don't go for the equipment anymore. Now I go for the people. What I learn from talking with others...

    Touch Less Automatic Chemicals

    I used the CPS-100 with a light blue tip for 3 years and it worked fine most of the time. There were a couple of times a year that it wasn't able to get the road film off. After I worked with CSI on their new setup, I was able to get the road film off during one of the challenging times. Then I...

    Touch Less Automatic Chemicals

    Now that the show is over and CSI has finally introduced their new soaps for touchless car washing, I can say that I have had good luck with their 205 mixed with 715 for lo pH and 224 mixed with 515 for high pH. I tested this setup for them in November and found it to be really close to our JBS...

    Touch Less Automatic Chemicals

    I run CPS-200 with a red tip, CPS-201 with a pink. In order to better deal with the eyebrow, I use CPS-104 with a light blue tip and CPS-105 with a pink.

    Laserwash 4000 Programing

    It's not unusual to use one product to look like a two step. It allows you to run the second pass with less chemical while maintaining show. It also gives your first pass more dwell time since it doesn't react with it. I run a lo/high two step and have to use a dwell between each product to give...

    Touch Less Automatic Chemicals

    For our areas road films, JBS's new two step COMPASS set up will out clean all of the tunnels around us. I also had success with CSI's experimental two step set up last November. The days where touchless was just a "maintenance wash" have been over since last year.

    Best Dryer Options

    We just replaced 3 with legs with Premier Dryers. They made the legs to fit the PDQ floor anchors. It made switching them a lot easier. Here's a picture of one.

    Laserwash 4000 Arch turning too early.

    This is usually a complex problem. The lw4000 goes around the vehicle on spot free by crossing the front of the vehicle until it sees the x24 left limit proximity sensor come on (treadleplate design) or until the VT card counts the proper number of pulses on the x30 width pulse prox and tells...

    Purchasing my first wash

    White works well because it says clean during the day and can be used at night to make the building glow, becoming it's own sign. You can even used colored led strips to make the walls change colors.

    Owner operater

    It depends. Your locations cater to people in one of two niches. Those that want to take the time to do it themselves and those that only want touchless washing. Most new tunnels can't win these people over. Focus on being the best self serve and touchless car wash and you should be okay. If you...

    Laser 4000 straight swivel

    Something on the Y-40 output card is blowing the fuse. When it does it cuts power to the Y-43 output which tells your autocashier to close the car wash bay.

    laserwash 4000 measure eye fail

    Hi Zal, The first thing to check is that the reflective material on the exit end of the right wheel stop (passenger side treadle plate) is clean and free of scuff marks. Next, with the bridge in the home position, make sure the photo eye mounted on the passenger side of the bridge is still...

    Chemical Overhaul

    I suppose the first question is what kind of wash do you have? Self Serve, Touchless IBA, and Friction all require different chemical solutions.

    More Presoak Discussion

    There are two ways to produce a clean car with a two step cleaning process. You can use an aggressive low pH that will simply eat through the road film and follow with a weak high pH to nuetralize and stop the low pH. This tends to produce a very consistent level of cleaning and a dryer car...

    Laserwash upgrades

    They make a stainless steel replacement bridge that comes plug and play. You just set it on the rails, install the J2 box and go. It takes about a day and a half to change. The soap is JBS's Compass Line. We have had a lot of success with cleaning using it. It allows us to match the cleaning...
