Use a broom to clean any dust or dirt off the tent.
Stretch out your tent so it lies flat. Take a towel and dunk it in the cleaning solution, then use it to rub the surface of your tent. If your tent is really dirty, use the brush to scrub instead of the towel. Dip it in the cleaning solution and scrub the tent. As you continually dip the towel or brush in the solution, you'll want to rinse it off occasionally. For convenience, use the other 5-gallon bucket for water.
Use the citro cleaner and the brush to scrub away sticky sap or adhesive marks.
