Recipe for Lugols dip

[Ziggy17]

I’m going to dip my torches today. I will likely use 1 litre of water, which is 25% of a US gallon. Can’t find a hard and fast recipe.

When I google it say 10 drops per litre, 40 per gallon. Seem correct?

What are you dipping them for, and what did are you planning on using?
