WD-40 Specialist Fast Release Penetrant Smart Straw 300g (21014 / 21112)

A fast acting penetrating oil that frees screws, rusted bolts and corroded mechanisms quickly, so stuck parts stop slowing you down. The Smart Straw lets you direct this penetrant spray at any angle into tight spaces like nuts and bolts, locks, chains, hinges, bearings and fastenings, then flip down for wider coverage. It works on metal, most rubber and plastic, alloys and most paints.
