FIRST, HERE ARE SOME DONT'S
Never wash your cover in the washing machine.
Never use warm or hot water to clean the waxed canvas.
Never have your cover dry cleaned.
Never use detergent, solvent or starch.
Never let your Outback GlamSwag sit in a hot car as the wax can melt and stain anything it's sitting on.
HOW TO CLEAN WAXED CANVAS
Shake or brush off dirt, sand or any other abrasive material
For small spots, use cold water and mild soap, and a sponge or brush.
With a little soap, gently massage the spotted surface.
Rinse with a sponge and cold water. Let the bag air dry.
CLEANING OF PLAID COVER
Spray Scotchguard on the plaid and leave to dry, then easy to sponge clean.
CLEANING OF INNER
The inners are dry clean only.
RE-WAXING YOUR OUTBACK GLAMSWAG
Depending on how much hard use your Outback GlamSwag gets, at some point you might consider re-waxing it. This can be done professionally or you can do it at home.
Only use Otter Wax or Martexin Wax, or an approved product made for this specific purpose.
To start, the Outback GlamSwag should be clean and dry.
Lay it as flat as possible on a table or the floor.
Place several sheets of newspaper inside the cover between the waxed canvas bottom and the cotton plaid top.
Using a soft cloth to apply the wax, rub down the entire bag as evenly as possible.
If the wax isn’t pliable enough, warm it slightly by submerging the container in warm water or wax the bag and then let it sit in the sun to soften and impregnate the canvas.
