Caring for cane and wicker furniture is not
a difficult process. If the furniture is made form good quality
raw material, it is a matter of wiping it clean with a cloth and
dirt can be removed with a mild detergent without harming the
cane or rattan.
For banana leaf, water hyacinth there is not
a lot you can do to maintain it and have you furniture last very
long as the products have a limited life span, especially in heavy
wear and tear areas. For woven plastic furniture(PVC and HDPE)
try and minimise its exposure to the sun. Although UV filters
are in most cases added in the manufacturing of the materials
sun will eventually wear down the product.
