Next time you are going to rinse the GG surface wash off the car. Try to start at the bottom of the car and work your way up. Just rinse with the width of the PW nozzle gets you. This is so you hit all of the surface with the water pressure from the PW. And you get a better cleaning ability when doing this. The dirty residue that you are getting the higher up you come has a better ability to run off a cleaned panel. And the chemicals is able to work till the water pressure clean it off the vehical. You might don`t see an extreme difference this way. But the benefits are a reason to at least test them out. Was a live video on Facebook I think that was linked here by Guz. That shows the rep from GG was recommend to use do it this way. I have used this method för a long time since we use alot more chemicals to prewash with here in Sweden. This clean with the water pressure from the PW from down and up is only when you have a chemical to clean of. With car soap and the last rinse it`s from top to bottom and I would even use the hose to do that step. So the higher water flow rinse off the car completly from car soap residue. This method was used with only a hose available too. And before the foamcannon and foam gun was being popular. It`s also so the dirt that has been rinsed off not gets clinging on the dirt that is being rinsed off lower down on the car. Was happy to see that Griots Garage has been looking over the pond how a prewash is cleaned off the car. The goal is to have as an effective prewash as possible before touching it with a wash mitt.
Since you feel like it worked as a touchless maintance wash says it`s the real deal of a dedicated prewash foam. You don`t get any near those results with a car soap. As that is made to be used with an aggitation to be as effective as possible to clean. And it`s the power from the PW that does the most cleaning and the prewash chemicals you use to clean the different dirt you have on the car is to help to desolve them. The goal once again is to get the most of the dirt off the vehical before you get that little dirt off with a touching wash. You can do a waterless wash or rinseless wash or a 2bm wash after the prewash. With a result you can see in a less dirty rinse bucket or cleaner mf wash towels. You get a safer wash and the risk of wash indused swirls is lower than if you don`t do a prewash step. Now I`m going to stop ranting over this.
Have a great weekend and wash safely LOL
