We have spent 2 hours scrubbing with a scrubbing brush) our caravan awning, (canvas) firstly with truck wash and then with Ajax professional, it is better, but still not good enough.
It has red pindan dust and stains from trees on it, can you help please.?
We have just returned from the Kimberley and the Pilbara, hence the red dust.
