[Veg Plot 1B]

Just go a 1,000 litre water container plastic inside metal frame type, which I intend to use to collect rain water on the plot.

Any suggestion what to clean with would be appreciated.

Depends what it had in it I suppose, if it was food stuff a wash out with warm water & some washing up liquid will suffice

I washed mine out with a very weak solution of jayes fluid.

Been used for collecting rain water bottom has black slim stuff from tree leaves.

In that’s case I’d put a splash of bleach in & rinse out well a couple of times
