Has there just been a fire at your home or office? If so, you probably have smoke and water damage in addition to the fire damage. Here is what you should right away:

Contact a local cleanup / restoration company (franchise) and ask them to come help you.

Place something waterproof between furniture legs and carpeting, to prevent corrosion or wood splitting of the furniture legs. Aluminum foil and wood blocks usually work for this.

Coat chrome-plated appliances and faucets with oil or petroleum jelly.

As much as possible, don't disturb soot particles because you don't want them to spread to un-damaged parts of the proprety.

Don't wash any painted surfaces.

Don't shampoo the carpet.

Don't send your clothing to a dry cleaner, unless they know how to safely remove smoke odor and soot.

Avoid cleaning electrical equipment unless you are qualified to do so.
