Recently a third party has used a powder extinguisher in our home. It was only used for about 1 second. I can't seem to clean it, and supposedly you aren't supposed to use water. I didn't realize this and I have mopped the entire floor. The marble looks faded and lost its shine, as did the wooden floor. Does anyone have experience? How worried should be about my electronics? There were non ein the hallway where it was used. Help would me massively appreciated!
