I guess the Oxiblaster normally works fine though right? I'm wondering if an old heavy 175 with a pretty aggressive brush might of made a difference?
I have 175 but not the brush , I have only few tile jobs and I try 3 deferent chem ( tilemaster , oxyblaster , Procyon ) and still looking for the best
Next one would be groutmaster

Oxyblaster is an alkaline similar to Groutmaster. Viper 2 is an acid that you would use when oxyblaster doesn't work.I use oxyblaster

I have a question. If dirt is already acidic why would you use an acid if an alkaline is not working 100 percent? Why Wouldn't you want to just choose a different alkaline chemical?

Not all contaminants are acidic. You do want to use an alkaline cleaner first for sure to remove as much if the oily soils from the grout as possible. 95% of the time a good alkaline cleaner will be all you need but when alkaline doesn't work this is when you move on to acid.
Moving from one alkaline cleaner to another will most likely make very little difference.
Gotcha. Just one last question. So say I'm doing a tile job. Groutmaster didn't cut it. Do I lay the acid rinse prespray down through a sprayer or do I run it through the solution line via the truckmount? And can it hurt anything if I lay down groutmaster prespray and rinse with acid through the solution line at the same time?

Just use clear water when doing tile to help minimize the risk of leaving a haze behind.
I use a pump sprayer when applying acid. Keep it low pressure. Make sure you don't get any acid on any stainless steel appliances and keep it away from walls and carpet too. I usually stay a couple inches away from the edges when using acid. Sometimes you need to use acid on the whole floor and sometimes you will only need it in a small area. The most common areas you will need it are by the sink or stove in the kitchen and in bathrooms.
One other thing, you can not use acid on stone floors. The acid will etch the stone and then you will be paying $4 a sq ft to have the stone refinished. When using acid the first thing you want to do is test the tile and make sure it's not acid sensitive. Go to a tile in a corner and put one drop of acid on a tile (not the grout) and see if the acid fizzes up on the tile. If it does fiz up then do not use any acid on that floor.
