Honestly, this depends on how they are cleaned. The alcohol / Aramith mixture leaves the balls more "squeaky clean" than Aramith alone and they actually are very clean, but throw quite a bit more. Dr. Dave did a really good video on throw impact of various cleaning methods. His video showed that balls cleaned with just alcohol throw A LOT. The Alcohol / Aramith spray mixture in my machine produces a throw about equal to that of a set new out of the box. Aramith cleaned balls clearly throw less, and balls cleaned with silicone compounds almost don't throw at all, but that changes as the cleaner residue wears off the balls in his video. The Alcohol / Aramith mixture was not part of his test though.
