My mother gave me a used Featherlite 3 horse slant load for Christmas. I love it but the dressing room smells very moldy, It is very bad now because of the mild and damp weather we are having. It will be horrible in July. The tack area doesn't leak but there is an ac/heater in the top. Any ideas on how to get rid of the smell and or mold without replacing all of the carpeting? If even replacing the indoor/outdoor carpet will even get rid of the smell.
If there is a filter in the heater/a/c unit replacing it may help. I know that is what they do sometimes in places like Florida when they get the mildewy smell. I would try and replace the carpet. Also, but I would wash it down with a mild bleach solution while the carpet is out to eliminate the mld in the cracks, etc. THen maybe get some of those "damp-rid" canister like things that absorb moisture and deodorize. I think you can get them at places like Lowes and Home Depot.
My tack room is moldy smelling, it gets really humid inside so I end up opening the door that leads into the horse stalls when the trailer is not in use to allow it to not get all humid and nasty. (It's a temporary fix until we can figure out a solution).
Be careful using bleach on true black mold. I met this couple that perform restoration services and mold removal and they said the fumes from bleach and mold were toxic.
Google mold removal and make sure you do your cleaning in a well ventilated room. You may want to contact a professional (there are a ton of restoration specialists in Joplin since the tornado) for advice.
I had boats up in Michigan that were stored over the winter and battling dampness through the winter was a full time job.
Do this after you have scrubbed the area out and have removed any bacteria growth. If you can provide electricity to your dressing room, hook a fan and a flood light to a timer to come on and off during intervals throughout the day.
The fan and light will provide a source of heat and air circulation to help keep the outside dampness from affecting your dressing room. Even if the room doesn't leak, the swinging temps between day and night will create condensation in the area. Combine that with a warm day and no air circulation and the condesation will turn into mold.
You can also try the containers of Damp Rid. Depending on the size of the area, you may need several and they probably won't last through the season.
