Fujifilm Finepix A345 Battery ChargerTips:

Most people have a few Fujifilm chargers. The chargers are for cell phones, cordless phones, power tools, small household appliances and any number of other things. The rust occurs if the coating on the charger becomes scratched, revealing the underlying metal. If the Battery Charger is then stored in damp basements or humid kitchens, rust may develop on the charger. In time the rust spreads, possibly making the charger inoperable. The first thing to do is to remove the rust as soon as it starts to develop.
• Scrub off the rust. Use a scrubbing pad to get rid of the rust on the Fujifilm Finepix A345 Battery Charger. This is the easiest way to get rid of surface rust and small rust stains.
• Apply mineral oil. Buy mineral oil from a hardware store. Use a paper towel to apply a small amount of oil to the Fujifilm Battery Charger. Wait 10 minutes for the charger to absorb the oil, then scrub of the rust using a scrubbing pad. Wipe the area clean with a damp paper towel. Dry thoroughly before using the Fujifilm charger.
• Use vinegar on the rust stains. Pour white vinegar into a paper towel and apply to the rust stains on the charger, then let the vinegar soak in for 15 minutes to 30 minutes. Scrub off the rust stains with a scrubbing pad and clean off the rust and vinegar completely. Dry the battery charger. White vinegar is a non-toxic home cleaning solution. The acetic acid in vinegar helps to remove rust stains.
