Pro tip: It’s easier if you regularly clean the canvas instead of letting that dirt build up too much. Either way, follow the steps listed below to clean your pop-up camper canvas.

  3. Depending on the product, you might have to let it soak in for a while. Once it has soaked in, you will then be able to scrub at all of the dirty areas. Use your soft scrub brush and scrub away any and all dirt and stains present.
  4. You will then just have to use your hose to wash away all of the canvas cleaning product, as well as the dirt. You should now have a perfectly clean pop-up camper canvas.
