nbc said:Well, I've been using this product called "Bona X", after learning about it from a friend in another forum. On the label, it says Bona X, Swedish Formula, Hardwood Floor Cleaner.
It also says:
Waterbased Formula
Cleans ALL Unwaxed Wood Floors
Removes Spots, Rubber Heel Marks, or Sticky Spills
Leaves NO Dulling Residue
Surprisingly, it removes practically all of the blue chalk staining, even cleans up the ferrule. I havent seen any bad effects on the shaft wood.
This is their website. Sells for $5.50 / quart. That should last you a long time....
