I live in a bedsit so bath tubs and washing lines are out of the question although I can get by using bowls and hanging the rucksack in my shower. I wish I had room for an embarrassing number of rucksacks!
Anyway, I got Grangers Performance Cleaner as recommended by the guy in Go Outdoors as Nikwax Tech Wash was for washing machines (but so is the Grangers so I don't know what he was talking about). It cleaned one strap successfully but the other one is still a bit smelly and needs doing again. I've ordered some
Grangers Odour Eliminator too which I think might help finish the job after a clean. What do you guys think of Granger's vs Nikwax?
