Now I am trying to be a cleaner and tidier person and was cleaning out DS's bedroom this morning when I properly inspected one of the wicker baskets that held some of his toys. It was literally green with mouldy dust. Totally unhealthy, it had been festering under his bed (my fault, he's only 3).
So before I threw it out, I googled cleaning wicker baskets. To my surprise I have discovered you can fully immerse wicker in something like a bath and some washing up liquid and after a quick wash it has come up like new!
Now going to find all things wicker in the house. Current basket is trying outside.
Thought I would pass on this gem of wisdom in case you want a new cleaning project that is very quick and satisfying!
