Darts Care
Cleaning the barrels
Accumulated dirt, skin acid, chalk dust, can build up on your dart barrels. This corrosive mixture is what actually eats away that original finish.
Skin acid is pretty potent stuff. As example, just look at how quickly a new penny, or polished silverware, tarnishes after being handled.
When someone's darts start to show wear, with knurling smoothing down, & the sharp edges of grooves becoming rounded, it is not usually just due to hitting other darts. The majority of such wear is simply corrosion.
To greatly extend the useful life of your darts, clean them regularly, and especially after eating any salty or greasy snacks. Any mild cleaner that can remove oil will do.
Removing all of that from your darts will not only make them last longer, but will also restore much of the grip by removing both the slippery feeling and the particles filling-in the hollows of the knurling.
The Points
To make sure your darts stick in the board as good as possible, roughen up the sides of the points ( not the actual point itself though ).
You can now buy gripper points that have ridges to help the points stick in the board.
