Since the hot weather started i have been saving the washing up water in a water butt, the problem is when i water the garden with it, it has a terrible smell. Is there anything i can add to the water in the water butt to hide or freshen the water??
Many thanks for your help, will try the peroxide if it does not work on plants i can always dye my hair blond with it. :)
