Re: use bulk formaldehyde as porta-potty chemical

[Michael McNeil]

We haven't had a caustic soda thread for a while.

(I wonder if it works for tree stumps. Where is the FAQs?)

Not really. From memory at the chem labs, sulphuric or hydrochloric acid is what eats up wood.

Now potassium nitrate IS good. Drill some holes and put it in and set a match to it. The wood smoulders away underground. Just top up with more nitrate every day...
