An awning is the softest, most stain-prone surface on the rig, and the wrong cleaner can bleach vinyl, fade acrylic or leave a chalky film. The useful comparison is what each cleaner says it dissolves, whether it names vinyl or fabric, and whether the formula avoids bleach.

The six picks range from a well-described Walex cleaner to bare listings that give only a name and a size. Each is compared on what its listing states, and any detail a listing leaves out is flagged as a check to do before spraying.

Before you buy

What Matters Before You Choose an RV Awning Cleaner

Key buying criteria so you get the right fit the first time.

  1. 01

    Vinyl or fabric

    Vinyl and woven acrylic awnings react differently to cleaners. The Walex listings name vinyl and fabric, and the MiracleMist names awnings generally. Look for your awning material on the listing.

  2. 02

    Bleach and discoloration

    Bleach can fade colored fabric and weaken stitching. The Thetford 1 Gallon lists a non-bleaching formula that will not discolor fabrics. Check for bleach-free language.

  3. 03

    Which stains it names

    Sap, bird droppings, mildew and road dirt each need different action. The Walex listings name sap, droppings, mold and mildew. Match the stain.

  4. 04

    Size and cost per ounce

    A gallon costs less per ounce than a 32 ounce bottle. The Thetford 1 Gallon and Walex Awning Cleaner Large offer larger sizes. Divide price by ounces.

  5. 05

    Thin listings

    Some listings give only a name. The Valterra 32 oz and Thetford 32639 say almost nothing. Read the label and test a hidden spot.
