Nitromors gives mixed results on Stone, last time I used it on a Flagstone to get the sealer off and it made it very Blochy, took an age of rinsing and Vaxing to get the Blotches out, Solvex from Ltp is virtually the same stuff as well, they both have dichloromethane in them which can give you horrible headaches after a few hours and thats with wearing a mask, they also ruin your protective gloves and make your hands very hot, so not sure whats going on there chemically.
Nitro-mors and Solvex are both listed as being Carcingenic < possible link to Cancer forming agents > so if you value your health keep away from it, I belive their is new legislation coming through from Europe next year which make sure these type of products can no longer be available and Im sure bith Nitro-mors and Ltp are looking at new options for a safer product, just a shame they needed a push from Europe to do so.
And if anyones asking we use Remove and Go for this job, although In the past I have used Aquamix Sealer and Coatings remover in the past both of which are not Carinogenic.
