What is the product warranty?

How can we quickly remove the annoying watermarks that are often left on the painted table after a wet teacup? You can lay a clean wet cloth on the watermark on the desktop, and then iron it with an iron at a lower temperature. In this way, the moisture that seeps into the paint film will evaporate and the watermark will disappear. However, when using this method, the rag should not be too thin, and the temperature of the iron should not be too high. Otherwise, the watermark on the desktop will disappear, but the brand will never be removed.
