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.
Plastic wicker, on the other hand, is equally popular. Aside from being inexpensive, it is also a low maintenance material that is weather resistant. The only disadvantage of having plastic wicker is that, due to its low cost, it is often mass produced look. The furniture you might be getting may not be unique, unless you customize it.
