get BROWN dettol, safe on plastics.... it can get a bit messy... clean the paint off in the solution DONT use water, it will make a horrible sticky substance..
after a good scrub in dettol you can put them in warm very soapy water (fairy liquid).... if you make a mess for whatever reason in the sink etc.. a little scrub with washing up liquid will clean it off.. leave them out to dry, if theres still some paint on redip them..
I'm not too sure on time i tend to leave mine in over night, i have left plastic minis in for over a week with no signs of anything bad, however it does weaken glue joins.
Dettol will stink out the kitchen/bathroom/garage but its a clinical smell so not too bad i'm sure the wife/gf/mother wont mind that
