The humidity level in S. Cal is never that high. I have yet to have anything get moldy or musty. Granted, if there is constant moisture from a water leak, that would be a different situation.
You can have moisture in the air without high humidity. There are plenty of California houses that have mold problems and not necessarily due to a water leak. Some houses may also be built poorly and allow moisture to seep into the walls, roof, etc. from the elements. Some houses have drainage problems that cause mold to develop where otherwise it would not. For example, mold grow in bathrooms that have poor air venting. And if you have a master bathroom next to your closet you must be all the more vigilant in preventing mold. Especially if you love taking long, hot showers that create alot of steam. Poor air circulation and lack of light also encourages mold growth.
Luckily our air circulation is fine. And although we don't personally have a water leak ourselves or any other problems that may cause mold, due to where the house is situated we get mist and fog quite often. There would probably be less moisture in the air in my house if we used the AC more. I just hate how drying the air gets if the AC or heater is constantly running. I actually use a humidifier the few times a year when we do use the AC and heater just so my skin and throat don't dry out. We also use a humidifier whenever our family members get sick. I'm also one of those people who constantly have to have the windows open. I love the fresh ocean air. Thank goodness we live in Calif. so that I can do that year round.
Like I said, I haven't had a problem with my bags getting musty or moldy yet but that doesn't stop me from worrying. Besides tossing a few desiccant pouches in with them probably helps and at the very worst sure doesn't hurt. I remember my grandmother used to use moth balls along with the silica pouches she collects (the kind you get inside leather shoes and pockets of clothes). I hate mold and I would rather do anything I can to make sure I don't get mold. Call it a mold-phobia if you will, but either way I would freak out if my H bags got any mold on them!
I think Ranag bought a H wallet and it might have had some type of mold on it. The mold was probably there before she got it but it grew and spread on her wallet. I felt so bad reading about her experience with that! Gosh, I hope that never happens to my H babies.
The old baby clothes were stored in a plastic box for awhile. Since storing them in cardboard paper boxes, they have stopped getting musty. I couldn't figure out why or how they got musty until reading an article from Martha Stewart's Living magazine. The article said that mold spores will grow and cause fabric to smell musty if they are stored in plastic. Now I know not to do that again with fabric, clothes, and purses!
With shoes, I still store them in clear plastic boxes but I drop a desiccant pouch in there as well. Desiccant is cheap, you can buy it at Michaels and for very little effort you get an added measure of security. I figure they come pre-packaged with my expensive shoes and clothes, then why not? If it's works for
Gucci than it can't hurt. BTW it's so cute that Gucci has its own brown desiccant pouches with the logo and everything. I wonder if H does that.
