It depends upon the type and fabric of the tent. However, usually, it’s hard for alone soap and water to treat these tents. Sometimes, you might require cleaning agents. First, you need to open the tent and keep it in an upright position. Then, shake, sweep, or brush out the loose dirt. Use a cleaner and apply the brush to get rid of further stains. Then, wipe it with a damp cloth or rinse the tent with clean water. Now, allow it to dry in the open air. However, the cleaning procedure may be different for different tents. It is best to follow the cleaning or washing instructions that have come along with the tent.
