A short while ago a friend of mine from my old RSB days posted in that group about a wonderful new product for cleaning shafts.
Mr. Clean's Magic Eraser is, as Fred suggested, one of the best things for shaft cleaning EVER!
Of course, as is usual with RSB, the blowhards had to start ripping at the concept before they'd even tried it.
Well the blowhards are wrong, Fred is right. I made my 15-year-old shaft look like new in about 15 minutes - and I did not raise the grain at all.
Thanks, Fred.
