Karachi: (RightNow) During summer, air coolers are an affordable source of cool air, but they often rust due to moisture. This rust can affect the cooler’s performance, especially in the water tank and metal parts.

To prevent rust in air coolers, some simple methods can be adopted. Firstly, do not leave water in the cooler and keep it dry. Regular water changes and proper cleaning are also essential.

For cleaning rust, sandpaper or a wire brush can be used. Scrub off the top layer of rust and keep the affected area dry.
