It's a smell thing for me too. I'll be using the case of blast I got as a 2 part stain remover in my dual chamber sprayer. Tried it a few times as pre spray and I just can't take the smell. Spot n Boost works real well and I love it, but again the smell hurts me, So I use spot n boost green on most stuff, then will pull out spot n boost regular if that won't work, normally just for ink spots.
Before Soils n Oils, I would be happy with encap green (or Intensity green) & peroxellent when needed. With soils n oils , I have one product that will do what those 2 products did.
