Need advice Mold

I bought a 2015 Heartland Bighorn 3010RE, we love the lay out of the trailer. About 8 months ago we had a lot of moisture in bedroom in the corners of the mattress. We took to a Rv mechanic and they could find no leak. So went home and a couple weeks ago pulled mattress out again and found a considerable amount of mold. And a couple of leaks in kitchen ceiling fan. We have only moved trailer about 10 times since purchased. But we are very concerned about mold. Any advice please.
Thanks a lot.

I have used vinegar to kill the mold.

Got to get the leaks fixed soon as the mold will not go away if it is wet. Have been following a bunch of threads where the major culprit seems to be the A/C unit. Seems the seal is not that great and with the weight of the unit it forms a depression.

Wet walls in the bedroom dont need to be coming from a leak. Condensation is most
likely the cause. Sleeping with a window open should help.

What do folks think about using a dehumidifier. If you set it at a reasonable humidity level will it retard mold.

that is to fix it. properly. quickly. you can possibly become allergic to the mold, and that could, in and of, itself be deadly. if not for owners, then maybe a visitor to the camper.

Wet walls were not stated. Wet mattress corners but not stated as to whether they were wall corners or where. Leaks were found at the fan. I would suggest you DO have leaks and had a very bad mechanic looking for leaks. You need to investigate further. If there were wet walls then I think you would see mold growing there also.

If we look at the floorplan for the OPs rig we can see that the head end of the mattress comes in contact or is very close to the walls of the slideout. The mattress also comes in contact with the bed base. Some mattress' will transfer moisture from the body and condense this on the cold surfaces it comes in contact with.
In a high humidity environment, a dehumidifier can help control moisture in the air, there by reducing the chances of condensation on cold surfaces, but has no direct affect on mold.

I have found that spraying peroxide on mold will get rid of it, better than bleach.

Be careful with mold. Disturbing mold can cause those spores to go airborne and cause huge health problems. Spend a few $ and have a pro look at it. We use two marine dryers that you can look at here WEST MARINE Air Dryer with Fan, Dehumidifier 120V AC | West Marine

Not sure where you live but is your bedroom area with the problem stationary or on a slide? I agree it may be condensation but if it raining and uou notice the moisture there may be leak. Look for any softnor bulging area where uou noticed the condensate. If you notice any a questionable area get it to the dealer asap especially if you have warranty left otherwise you may have to foot the whole bill.

. may be bpicking

My removal suggestions, should you want DIY removal. Home depot has a gallon jug of bleach based chemical that's pretty good on mold. Use long rubber gloves that go up high on your arms and a good respirator mask. a couple plastic spray bottles to apply the chemical. Rags, a brush, etc. to help with removal. All available at home depot. Wear long sleeved shirt and pants, etc.

You have to understand mold in order to correct the problem.

Firstly, mold needs several things to propagate.
1. Moisture: (wet, damp, humidity)
2. Food source: (Fiberous materials i.e. paper, wood, etc.)
3. Darkness: (No sunlight)
4. Stagnant air: (No air movement)
If you take away any one of these, mold will not grow or survive.

Mold is not seen. If you see black, that is the feces of mold. If you are discovering mold in a well lit area, it is likely the source or growth is happening on the opposite side of what you are looking at.
Any topical cleaning will not be dealing with the source and it will continue to grow and reappear in this case.

If you discover mold and cannot deal with it right away, cover the visible area with plastic and tape all edges. Any air movement in the affected area will cause the mold spores to become air born. You should be wearing a respirator to do this or at least a paper fiber mask suited for it.

Mold spores are known to cause respiratory issues and in some cases have been known to be fatal.

Once you have made the area safe. Look for the source. This can be any number of things. There HAS to be a source!

1. Most intrusive - Water ingress do to a failed system such as caulked seams, failed joint seal, etc.
Make the appropriate repair. However, cleaning up the mold situation will likely require the removal of surface materials or portions of the interior envelope and should be handled by someone with knowledge of dealing with mold. Simply removing wall paneling or ceiling panels will contaminate the rest of the structure. The area worked on should be emptied, contained with poly and ventilated to the exterior. Affected interior wall/ceiling surfaces should be cleaned, hepa-vacuumed and treated with an anti-microbial or mold inhibitor and then sealed with an encapsulant.
Once again, I recommend a professional for this. The resulting repairs can be done by anyone.

2. Least intrusive - Humidity or condensation due to climate. In this instance, topical mold will grow however stills needs the above earlier mentioned properties to grow. If you live in a moist, humid or cold climate you need to deal with the problem by dehumidification. There are several mechanical systems such as a dehumidifier and other systems such as Drizair, available to combat this.
In cold climates and when the unit is stored, make sure that cabinets, drawers etc, are open and able to be accessed by your dehumidification process. Pull mattresses away from walls and curtains or blinds away from windows. Frost has a tendency to build up in these instances and leads to a mold issue.
If topical mold is found, tackling this type of cleanup is more suited to the average individual. Again, wear some type of protective mask. Use a cleaner with an anti-microbial additive. Any material that has become moldy will not likely survive a simple washing or dry cleaning and will usually always be stained and retain a musty/moldy smell. You're better off replacing it and yes, this includes the mattress.

Just in case anyone wonders where I get this from, I'm a certified water technician and a Senior Manager with a Disaster Restoration firm.
I work with this type of situation every day.
We do not recommend any "home remedy" cleaners such as bleach or vinegar. Bleach can be dangerous for a multitude of reasons in the wrong hands and vinegar doesn't work.
