Write the next sentence in this paragraph:

How to clean carpet without a carpet cleaner
Address stains immediately.
Do not let stains sit on the carpet for a long period of time. Clean up stains right away so the stain doesn't absorb into the carpet fibers.
Stains that sit on the carpet can also end up leaking into the bottom of the carpet, causing mildew and odor. If you know people are going to eat or drink around the carpet, have cleaning materials on hand in the event of spills and stains.
