Pan cleaning?

[ShaunG]

What's the best way to clean the burnt sap from the pan?

Vinegar and water. Heat and let it set overnight and scrub in the morning with a SS scrub pad.

I agree, except not with a SS scrub pad, that will scratch the pan. Use a non-metallic scrub pad or a copper one, that is softer than the SS. If you scratch the pan, cleaning will be needed more frequently from then on.

A piece of copper pipe with the pounded flat works good as a scraper.

Sounds like someone, not naming any names here, just became one of those true sugarmakers! Mainly elbow grease or mechanical tools if it really gets bad. BTDT. I have seen some bad ones. Hope the pan is still ok.
Keep boiling!
