You can drive yourself crazy with this stuff if you want to. I use ultrapure water myself. Bulk of it is in a 1 gallon glass lab container. I transfer it into an old RRL SVW plastic bottle that's more manageable when it comes to actually cleaning records. Load up the steamer with it and what doesn't get used sits in the steamer til next time when I usually just top it up.
Works for me. The results are excellent. As Crem says, it makes sense to start with the cleanest possible water and I know I have that, so I don't sweat the small stuff.
