In reply to UKH Articles:
I wondered if I was preaching to the converted with this article, if people really needed telling all this. Then the night before last I pitched my tent in a layby near Loch Maree (yes it's still legal up there). Noticed a bit of a smell but it was too dark to see and I had a cold, so it didn't strike me what the smell was - I actually decided it was just the smell of the tent fabric (unbelievable in hindsight). Then I packed up in the morning and discovered a - presumably human - turd squashed under the groundsheet. No paper. Right out in the open beside the road. It never ceases to amaze me how disgusting some folk are.
I don't care what the washing instructions are - the first thing I did when I got home was to stick the tent in the washing machine.
