So, Dh and I decided to get some shelves in there.  DH was reluctant to just put some up, being as our electrical panel was in there, so we compromised with a 'laundry rack'.  This helped us to get such things as the bleach off of the floor, and provided hooks to hang wet clothes that cannot be tumble dried on.

As you can see, we are already using the hooks!  In the middle is a basket, in which I put the laundry waiting to be washed.

LOOK!  No more clutter on the floor!  There is a mop bucket there, but nothing else.

I was even able to move some of my cleaning products from elsewhere... such as the binbags (trashbags).  They were eating up space in my food cupboard, but now they occupy a shelf on my cleaning rack, and I can fianlly put all the food back where it belongs!
We're not sure about the final configuration of the shelf... it is adjustable and the drawer, hooks and shelves may end up in a different position.  For now, it is a central, easily accessible (to me not the kids) location to put my cleaning stuff.  Nothing on top of the dryer (leaving me a place to fold clothes) meaning no more bleach accidents!!
