Make your darts last longer! Most of the wear on a dart is not from hitting other darts. The knurling and grooves wear down from contact with skin acid, salty snack residue, etc. Clean your darts regularly with soapy water, or a household ammonia cleaner like Windex. This will remove the acidic oils from the darts, and make the machined grip last much longer. Removing the oils from the darts will also enormously improve the feel, making them much easier to throw!"
