To clean the party tent:

  • - Lay down the fabric on the ground.
  • - Spray it lightly with a 95% Water, 5% Soap mixture
  • - Clean it using a car sponge
  • - Dry it completely before storing it.
  • - Store in a dry area

Always use the proper installation and dismantling techniques which are listed in your instructions manual. Using stakes and/or weight bags on your party tents will greatly increase wind resistance and is always suggested! Know that even the best party tents can only withstand wind up to a certain point. If you feel you're getting close to that point, we strongly advise taking down the party tent before it gets damaged!

Follow these tips, and your party tent will last you for years, and years to come!

We appreciate your feedback!

"Great quality! Great price! I’m so happy I chose ThePartyTents 4 years ago when I bought the first tent for our hotel! We now have 15 tents and all of them are from PartyTents’ Store. Looking forward to doing business with you guys for a long time!"

"This 20’ X 32’ Tent with the upgrades I got is just excellent! It holds up in the wind, it keeps the sun out and gives us shade, and it’s fantastic for all of our parties like our 4th of July Party!"

Dina S. - Miami, Florida

"Let me tell you what kind of company this is. It was early covid, and EVERYONE was sold out on tents. My business was bleeding, and thank God for thepartytents! They had the tent I needed in stock, delivered it quickly and my restaurant was able to stay open ever since! Thank you again!"
