Lifespan of a Loofah Sponge?

I'm guessing you can use it as long as it isn't falling apart. I don't think it really has a expiration date on them. If they last forever just think it saves you money from buying more. Maybe sterilizing it with bleach once or twice a month will help with germs that might build up in them.

I notice that you have a puffy in the picture, not a loofah. Which one is it? Loofahs are gourds, and last quite a while. I think that you need to periodically rinse it in bleach water to kill anything else growing in it. I have heard of people getting skin infections from not doing this. The puffy needs to be bleached or put in the microwave. I do not know if the loofah can be microwaved or if it would be damaged. Have fun with the bubbly new gels.

In the wild, they last 2 - 3 weeks owing to predators etc, but kept in captivity in a nice warm bathroom, fed regularly and given bubble bath tops to play with, they can last 2 - 3 months, same as haggises (or is that haggi?) Unlike Gremlins, they MUST be given water, or they go hard and fall apart. Like my one did. Sweet, dear likkle Benji, too young to die ...
