We use EaCo Chems products all the time.
Be careful about the the Glory getting on aluminum, you might want to cover it, or spray some Sabre on it before you apply the Glory to neutralize it (Sabre is the same thing as Brightenol & Glory is the same as Cleansol). We don't do truck washing, we typically stick to cleaning buildings and such, but we have done that kind of cleaning before. The competative pricing can be brutal in that end of pressure washing.
Glory is an excellent cleaner, just be aware that it is not your typical harsh caustic or butyl based cleaner, its much better for the paint and the final appearance is superior, but the application is much different. It takes a double application with no rinse in between chemical apps. to achieve the brushless cleaning results, if the road stains are very harsh you may have to use higher pressure, higher ratio, or longer dwell time, (50:1 to 30:1 is typical) and some brushing may be needed, depending on the stains and your idea of clean.
Once you get the hang of cleaning with EaCo Chems detergents, you should be able to move just as fast if not faster, with much better cleaning results. Caustics and Butyls strip thin layers of paint off each time you clean, with routine cleanings the paint suffers tremendously.
Having to move and clean 25 trucks and trailers is gonna take more than half a day by yourself. The moving alone is gonna take some time.
To find the nearest dealer (sometimes its cheaper to order straight from EaCo Chem) give them a call. Ask to speak to either Mike or Lynn. They are all friendly and helpful. They can also help you out on any application and method questions you may have.
