Does anyone have any advice for keeping the feed rollers clean on the dewalt 734? I have tried wiping them down with acetone and have had little luck with the cleaning lasting. I did spray down the table with some lubricant which helped for about 4 or 5 boards until it all got soaked into the boards. It doesn't seem to matter on the wood species. I have been running white oak, soft maple, poplar and even some pine. I only take about 1/32 cut at a time.
