When using marshmallow fluff, one thing to remember is that it is extremely sticky, and may actually be a turn-off until you're well into it as it can be uncomfortable on bare skin and body hair. The trick? Add more! Once you begin moving it around and it coats you fairly well, it will take on a very silky texture and while it clings well, once slightly warmed up by the body, it will slowly run down and the texture will turn smooth and shiny. The outermost layer will slightly firm up in time, but will never actually harden even if you leave it on yourself for an extended period. It stays silky and pliable as long as you keep moving it around.

Be mindful that it can sting a bit if it gets in the eyes.

Cleanup is easy as it's generally made from egg white and corn syrup. Both of these ingredients are water soluble, so simply standing in a hot shower will eventually clean you off with no residue or lingering smell, and if you accidentally drip any on floors or carpet, simply hold a wet cloth over the spot a moment and you'll be able to wipe it away.
