Ditto best left overnight (sealed container to reduce the smell) Rinse warm water and toothbrush scrub, Bob's yer Uncle!And Australia based? Yeah we have dettol lol.. Thanks
If you can get it in Oz, fairy power spray is awesome (better than dettol in my opinion). Works great on plastic minis, BUT I've not tried it on resin yet, so test on a scrap piece first.
