on canvas
 

The first step in removing mould is to let the canvas dry to kill the mould & then brush the effected areas with a stiff bristle brush.

To neutralise the spores add two or three drops of oil of cloves per litre of water & spray the area & let dry. Oil of cloves is available at chemists. You can also try 20 to 50 millilitres of white vinegar per litre of water on black mould. It is a good idea to try any procedure on a part of the canvas that is not in plain view.

For spots of dirt on canvas you can use grated Sunlight soap which is first added to boiling water to make a paste, then add the paste to water & mixed it in. Hose the canvas down & gently brush on over the effected area with a soft bristle brush, finally hosing off all the soap. Do not use detergent.

Anything stronger like a commercially available mould remover may remove the waterproofing from the canvas, so you may need to apply a canvas resealer.

If you need to reseal your canvas check to see if there is a tag sewn onto it canvas, mostly around the doorway, with canvas manufacturers name & care instructions. If not, give the camper trailer manufacturer a ring & ask which canvas waterproofer they recommend.

There are two types of resealer. A silicone based type like Aqua Proof which is water washup. If used on the wrong canvas type it can leave a milky residue, particularly noticeable on dark coloured canvas.

The another type of resealer is wax based like Dry Seal by Joesph Lyddy & washup in mineral turpentine.

Klaus from InFront Camping has BellaProof brand waterproofing suitable for Bradmill, Brella & Birkmyre Canvas. http://www.infrontcampinggear.com.au/category36_1.htm

The easiest way to apply waterproofing is with a small roller. Only apply a small amount into the tray at a time & always mix the contents of the container before tipping into the tray.

Always try any of the above on a small area of canvas which cannot be normally seen.
