I just spent a week up at Inskip and we were going through a tin of rid a day until a couple camping next to us suggested we give their concoction a go. It work a treat with no more bight resulting.
The recipe is as follows,
100ml of Detol
100ml of Sunscreen (to give a loose creamy texture)
100ml of baby oil.
We now use this at home and have ditched the rid and aeroguard.
Give it a go you wont be dissapointed.
Good luck
Cheers
Mark
