Your sponge can last years if taken care of properly.
Caring for your sponge:
Every few weeks, soak your sponge in 1 cup warm water with 1 tablespoon baking soda for 15 minutes. Then rinse and let dry (preferably hang it in a mesh bag.) The baking soda cleans the sponge as well as revitalizes its cellular structure, increasing durability.
After each use, allow your sponges to completely dry. Don’t keep them in the shower, hang them somewhere were they can totally dry out.
To disinfect your sponge:
Soak it in 1/4 cup hydrogen peroxide and 1 cup water, this will clean and re-bleach the sponge.
Soak in 1 tablespoon apple cider vinegar (or white vinegar) in 1 cup of warm water.
Soak your sponge in 3 drops of tea tree oil in 1 cup of warm water, this will eliminate any odors.
*Never place your sponge in boiling water, a dryer, or the microwave. This will make your sponge hard. Don’t use bleach, this will weaken your sponge. Don’t twist or pull your sponge, this will tear it. If your sponge starts getting ragged, trim off the loose pieces with a pair of scissors.
