Before you use canvas that is riddled with mold, dry and remove mold and mildew spores to prevent sickness and improve the fabric's look. The process is simple but requires several steps to ensure all the mold and mildew are completely killed and removed.


Difficulty: Moderately Easy

How to:

Things You’ll Need:
  • Canvas cleaner
  • Cloth or cleaning rag
  • Hard-bristled brush
Step 1
Dry the canvas in direct sunlight. Drying out the canvas is necessary to eliminate live mold and mildew spores, which thrive on moisture and damp conditions. Target areas where mold is especially visible.
Step 2
Brush the canvas with a hard-bristled brush to uproot dried mold. Vacuum the uprooted pieces of mold, or continue to brush the mold away.
Step 3
Apply a mixture of one part rubbing alcohol and one part water to the canvas. Apply to areas where there is mold or where mold was brushed from the canvas. Pat the solution onto the canvas, allow it to penetrate the surface for five seconds and then briskly scrub the area.
Step 4
Obtain additional waterproofing if necessary. Removing mold and mildew stains might compromise the integrity of a waterproof coating on canvas. See manufacturer's instructions for obtaining a waterproofing product.

Tips & Warnings

Never use bleach or other abrasive chemicals on the canvas of a pop-up camper to remove stains, mold or mildew.
