All you need is a garden hose or watering can, a large plastic tub, a small cup, warm soapy water, and some cheap toothbrushes. I like to clean my chotchkies ... also known as chachkies and tchotchkes (take your pick) on my back deck. Makes less of a mess than if you do it in the house.
Let me start with my favorite garden fairy. By the end of the season she was looking pretty dirty and a bit weather worn. First, I gave her a good dousing with the garden hose. Then I filled up a large basin with warm soapy water and let her soak in it for awhile.
After about 5 minutes, I took her out of the tub and rinsed her off with the hose. A word of advice - the spray from the hose will not get out every bit of dirt. That's what the toothbrushes are for. Then I dipped a toothbrush into a small cup (also filled with warm soapy water) and scrubbed every little nook
and cranny well. Then another good rinse from the garden hose and ... done! Let air dry and pack away until next summer.
One down and .... only thirty more to go.
Happy Gardening ....
