WD-40, the multi-purpose lubricant derived from a product widely used by NASA, now comes in four specialized formulas to be even more effective and resolving in your home, garage, workshop, and garden. Alongside the classic "miracle can" whose qualities we have repeatedly tested and described—here offered in the larger 500 ml format—three new 400 ml versions appear, with formulas optimized to enhance effectiveness in specific situations. You can find them in DIY centers, hardware stores, and well-stocked home improvement shops.

Fast Drying Contact Cleaner
Specifically formulated to clean and restore electrical and electronic equipment: printed circuit boards, switches, read heads, printers, photocopiers. Remember to disconnect devices from the power source before use. It effectively dissolves dirt and dust without leaving residue—the potentiometer on your old amplifier will return to original functionality. It respects delicate materials and removes solder residues. To restore a faulty contact, first remove the causes; a subsequent spray preserves against possible malfunctions. It prevents condensation formation, is non-conductive, and evaporates quickly, making it suitable for preventive use on circuits, such as your car's fuse box.
