I've had my saw about a month now and love it. The only problem I've had is with the table top. There are some spotches that were there when I opened the box. I thought it would be no problem to clean them up and go on, but it seems that they have resisted all my efforts to remove them. I have tried steel wool and even some light sand papering with and without WD40. Now they seem to be growing even though I have waxed with Minwax after each try. Any suggestions?
