Depends upon how much vinegar you added to water ect. Usually you can take them out in 24 hours and put in grass on ground in shade and cover with damp cloth and you will be surprised how fast they will rust. Leave them for three days or so as your first days rust is usually very light even though you can see a covering of reddish brown rust. This rust you can rub off with your finger easily so let set for three days to let rust lightly pit traps. Anymore questions fire away
