Hey, I was wondering if some of you all that's been washing trucks for several years can give me some advice? I washed my first trucks last week, had to brush the trailers in every spot, you could tell any spot that wasn't. I thought to myself there must be a better way, I know about 2 stepping but have never did it. I used Steven Rowlett's, Rowlett Pressure Cleaning Service RPC 121 ATLAS Truck Wash to Wash the trucks, diluted at around 50:1 with Hot Water set at about 145 degrees. It's more of an all purpose truck cleaner(supposed to clean I mean), that's safe on all metals. I might as well not of used any soap, you couldn't tell the difference. The cabs I ended up having to hand wash with Dawn diswashing detergent, they looked good, but man it was a work-out, so was the brushing on everything too. By the time I got done, I pretty much worked for about $10 an hour, lol, and worn't out too. I use Steve's products all the time, and he has some caustic truck washes and acid too, but he told me to use the ATLAS. He doesn't like to sell acid wash to someone starting out, and I can understand that. I also bought a Citric Acid based aluminum brightener which I haven't tryed out yet. With acid washes I'm concerned about what I read with messing up windshields and on polished aluminum and chrome. What chemicals, procedures, dilutions and anything else should I use. Any help you all can give would be greatly appreciated. Thanks
