Technical Questions Tsp substitute vs cleansol bc for oxidization removal
When I do oxidization removal, I prefer to use cleansol bc because it's always worked well for me. However I have a quote to prepare for approximately 30k sq ft of metal siding paint prep, and that would require a staggering amount of cleansol bc in my experience. With tsp substitute being far cheaper, and what this company that I will be paint prepping for prefers anyways, I'm thinking about giving it a try. That being said, I have questions since I never used it.
Can I mix it extra hot and downstream, or would it be best to batch mix and apply with a 12v pump?
Does anyone have any methods for creating on demand warm water for mixing on site, instead of having to find a mop sink to fill at? (It's a commercial property)
Once it's mixed, will the tsp stay as a solution even once the water cools off?
How does the performance compare between the two?
Anything else I should know about tsp, or alternative solutions for ox removal and paint prep?
