Over a period of time wicker furniture and cane furniture can become out of shape. This is generally due to the cane or wicker stretching. Here are a few tips for rejuvenating your wicker or cane items:
If your cane or wicker chair is starting to sag then sponge the cane with a hot solution of half vinegar and half water. Place the chairs out in the hot sun to dry. You will find that the sag will tighten up.
You can also use hot soapy water that has a cup of salt added. Then leave the furniture to dry in the sun for a few hours.
Even the following will work. If your old wicker is looking and feeling a little saggy, all you have to do is wet down the furniture and let it dry in the sun.
With all of these tips the heat will shrink the wicker or cane which will put back the stiffness creating a better look and feel for those nice warn nights on the porch!
