Best way to clean canvas

Warm water and elbow grease.
Do NOT use detergent or dish washing liquid if you want it to stay waterproof.

Learn to love the blemishes on your canvas. They're a constant reminder of your past trips. Can only reinforce the previous comments about detergent.....DON'T! You'll never get the canvas waterproof again.

Enjoy them, you've earnt them. Cheers Mick.

NO DETERGENT - as above. Hose and a soft broome will do the job.
regards,

I'd try blowing (compressor) it down using a brush/broom first..As Micko stated a slight stain wont hurt lol..People state they use products without adverse affects but i wont use any on my swags,water only..

Thanks guys, the CT is very well used and we have never washed before but thought we better give her a treat. Cheers
