With your non-plastic items out of the way, begin cleaning your plastic furniture by spraying off the loose debris and dirt with a garden hose. Using the high pressure setting, spray all areas including the sides, bottoms and any crevices where dirt gets trapped.
The waterproof nature of wicker also means that if you spill something on it, the liquid will tend to just drip right through to the floor. With other woods, it may cause a stain, but not on wicker. Even though wicker furniture looks substantial, it’s easy to move it around. That’s a real bonus if you like to rearrange the patio furniture now and then to suit your entertainment style.
