Preserve Your Patio Set
WD-40 is a blessing for patio furniture. Metal chairs and tables may be cleaned of rust and oxidation. It can also be used to protect plastic furniture against sun and rain damage, which can cause cracking and color fading.
Simply spray WD-40 on the plastic and wipe it clean with a dry cloth to protect your furnishings. If the furniture has already been harmed by the sun or other conditions, a little WD-40 will restore the lustrous surface.
