Persinally, I use Persil. Wonderful for those hard-to-shift bonfire stains . . .

Get a goat. It can then eat the evidence.

Each which evidence? The bonfire or the clothes?

Oh dear - I'm not as inconsiderate as all that! The fire lasted about 20 minutes - I put it out once it had all burned away and the smoke cleared pretty quickly. I use Tesco's own label non-bio. It smells nicer than Persil (and I used to be a Persilite).
Are goats good to eat?

Goats' cheese is good.
