I have been following the thread on cutting irons in water. My question is, why distilled or purified water rather than tap water? I was under the impression that purified water, i.e. ultrapure water, is much more corrosive than mineralized water like spring water or tap water. In fact, ultrapure water is so corrosive it is often used in clean labs as a cleaning medium for surfaces. Also, the pharmaceutical industry no longer uses stainless steel tubing for ultrapure water because of corrosion -- they use Teflon or polyethylene instead I believe. Wouldn't pure water be worse on iron oxidation than "mineral" water? I can understand using pure water to cut down on trace element contamination for geochemical srtudies, especially on stones, but I don't see how this helps for keeping irons from rusting. Also, while we are at it, what is the best blade for cutting irons?
