Like all toys, wooden toys can also get soiled and need to be cleaned. But you need to remember that wooden toys shouldn't be cleaned the same way you would the plastic ones. Here are some steps to follow to clean them properly.
How to clean painted or finished wooden toys.
Use an anti-bacterial liquid dish detergent and moisten a sponge just until suds are evident. Wash the finished or painted wood toy with the soapy sponge. Don't soak wood toys. Soaking causes the wood to swell, which can lead to cracking and splitting of the paint, finish and/or wood.
Rinse quickly beneath the tap. Don't saturate the toy. Dry thoroughly with a clean , soft towel.
If there are stains, mix a solution of half white vinegar and half water in a spray bottle, and lightly spray the toy. Scrub the stains with a clean sponge. Dry the wood toy or teething object with a clean, soft towel until dry. Once the vinegar dries there won't be any odor or residue. Vinegar is completely safe and edible.
Cleaning Natural or Unfinished Wood Toys
Moisten a clean sponge until damp. Wipe the natural, unfinished toy or teething object with the sponge.
Apply rubbing alcohol to a cotton ball until the cotton is damp. Rub the unfinished wood toy all over with the alcohol-moistened ball.
Dry the toy with a towel. Never use a heat method to dry the toy. Heat will dry out the wood and will cause the toy to crack or split.
If there are stains, rub the stained surface of the wood gently with fine grit sandpaper. Remove the sanding debris with a damp sponge. Dry the toy with a clean, soft towel. If you want to protect the sanded wood you can rub the wood toy with a little salad oil on a cotton ball. Allow the oil to absorb and dry before returning the toy to the child.
