Dirty old barrell.

[Puganded]

Have a barrell that I last used 4 years ago, been in the garage with open lid.
What's best to use to deep clean ?can't get hand in it!

Bleach,then oxi.

This might depend on whether it was clean when put aside or just left with something inside. Unless it was cleaned before storage I think I’d be giving that a long hot caustic soda soak to start.

I've just done one of mine with a weak bleach solution, hasn't been used for a few years but has come up a treat.
