We use Distilled in our floor steamer, detailing steamer and my wife's hair steamer . Since we always have at least a few gallons on hand, I dillute all my products with it...just because I guess. In the Rinseless buckets...I agree with Chase, it's probably overkill unless you have some really bad (like iron infused) tap water. My old house in Virginia had water so bad that if the sprinkler hit the siding on the house for 5 minutes it would be red/orange, haha.
