As most of you would accept, all water is not created equally. I live in Washington, DC, a place with notoriously hard water. Will the hardness of this water have any extra adverse effects on my razor and/or Norton 4k/8k hone? If so, are there any special care instructions that anyone can offer? A buddy of mine suggested that when I eventually hone, I do so with distilled water...seems to make sense, but I wanted an expert opinion.
