Just a comment about this chemical: while it certainly is an oxidising
agent, the brown stain is a by-product of the oxidation rather than a
'char' of the material being oxidised. I think it is Manganese Dioxide,
somewhat similar to rust: if you've ever tried to get rust stains out of
fabric you will recognise the kind of persistence.
Another oxidising agent is Sodium Chlorate, which is used over here as a
total weed killer; if available, it may be a bit cheaper. I have only
used it to wake up a fire of damp cardboard (clearing out a basement) -
but it did that job a treat, even though claiming to have been treated
to make it less dangerous as an oxidiser.
