Mildew in a Howling Moon

I can recommend something that definatley works, it's called Mildew Cleaner & Stain Remover by Rule/Sudbury.

The above works great on canvas even coloured canvas, we did a complete camper trailer that was extremely bad/covered in mildew and it removed every trace of it. Just make sure you read the directions and you can't go wrong.

Hi Bat,
I diluted Pine-Clean or Detol with water. Set up the tent and brush it all over, inside and out, then let sit and dry. Best to let the tent stand for a few days. Check and repeat if necessary.
Worked for me.
Cheers,
Mike

my swag has mildew instructions I am not at home but i am sure it says just brush it off and for more intrusive attacks use dilute bleach and I think it mentions resealing the canvas if a fairly large area is treated
