I recommend RODI water for rinses. Especially if you live somewhere that has very hard water like I do. The calcium can build up on and around the lens (moreso in the grooves where the lenses seat) when the water evaporates and can lead to micro scratches while cleaning.
Even if you don’t live in an area with high water hardness levels, you never really know what’s in your water supply unless you go to your local utility company and ask them for their readings.
Using RODI takes the guesswork and hassle out of the whole thing because it’s arguably the purest water you can get unless you’re ordering lab grade purified water, which in that case you’re even more adamant with protecting your lenses than I.
