You can almost bet that if the manufactures of EBC are warning you off using their product near aluminium you can be sure it has a corrosive in the formula that will etch the aluminium. The main reason why I like the fleet wash is because you can be 100% sure that your average truckie isn't going to use a product on their beloved truck that is going to harm it in any way. Fleet wash is good with paint and glass and even if you have to go over the job twice it's still better that stuffing the aluminium with a corrosive. I read the postings on here where guys are mixing this chem with that chem and creating "Formulas" which amuses me no end. Are they Pressure washing experts or Industrial Chemists. Each to their own. An 'OFF THE SHELF" product is my motto that way at least if something goes wrong you have someone to turn to or blame, what ever the case may be, if there are any issues. Why reinvent the wheel???. It's a bit like what I read about "ROOF SNOT". Best thing since sliced bread and probably paying a premium for it. If you go to you cleaning products supplier and buy MYRISTAMINE OXIDE it's the similar rose with a different name and it is thickish treacle like substance almost like ??????......SNOT!
MYRISTAMINE OXIDE is a soaping or foaming agent that is used in a wide range of cleaning products as a surfactant. It is also VERY COMPATABLE with HYPO. HYPO mixed with water is a very WET mix. Down stream it on its own and it will practically run straight of the job. Put some "WONDER DUNG" in it (MYRISTERMINE OXIDE) and you have a foamy, soapy, clingy, more hang time, dwell time cleaning agent. Bingo!
Hypo isn't a cleaner it is a bleach, stain remover, disinfectant, deodoriser, water treatment agent It's not a Cleaner (detergent or soap). It is of course great for bleaching out MOULD and it will kill moss by bleaching out the green in it which of course is what keeps the plant alive, it doesn't actually CLEAN in the true sense of the word it just bleaches the colour out so you can't see it. Add a soap or detergent to the mix and that's what does the cleaning not the HYPO. Dish washing liquid, providing it is HYPO friendly, will do the same job as any WONDER DUNG you care to add to your House Washing Formula.
Sitting back here in NZ waiting for the sh!tstorm.
