<human>:  What is the best way to clean and preserve an antique vase?
<bot>: The best way to clean and preserve an antique vase is to use a soft, damp cloth or sponge and a mild soap and water solution. Do not use any abrasive or harsh chemicals to clean an antique vase as this could damage it. Allow the vase to completely dry before applying a protective layer of lacquer or wax. This will help protect the vase from dust, dirt, and damage caused by everyday use.
