hmm,,, not to get agrumentive here Ms Hitman, but Mr Gates is correct. While the MSDS sheets do state a content in percentile of "abrasive powder", you must look at the overall composition of the solution. Then comes a long and chemically invovled reaction with such things as acidic bases and free radicals, leaving the determination of ,, the availability of either, "dissolved solids", "solids in suspension", or a coagulation of abrasive solids. Beyond all that you have to consider if the "abrasive" in solute is harder then the material being cleaned or is it not.
Basically it boils down to ,,if all abrasive material were to corrode what it came in contact with,, the "hard" barley,sugar, and yeast, that is dissolved into water to make what we Canadians call beer <!--emo&

'><!--endemo--> would actually hollow us out rather then give us a large belly shaped protrusion we claim bragging rights over.
Also while "Flitz" is not measurably abrasive to ferrite based metals,ie stainless steel. It might be abrasive to a salt based metal, ie zinc or aluminium.
No hard feelings please. <!--emo&
