    - Hi, while I appreciate your response that seems to cover wall units in general, I need more specific guidance to clean a Mitsubishi split system,Mr. Slim unit, model MS24WN. The problem is that there is minimal clearance to get through the narrow opening to clean the fan, etc. I assumed my post would include the specific model. Perhaps it didn't. I look forward to your response. Thanks, Kevin

    The gaps in the fins and grill are less than 1" x 1" across the entire opening. How do I clean the insides given this limited, restricting access please? Also, is it easier to clean the fan debris dry or wet? I appreciate your responses!!! Kevin

Use Bleach and water about a 25% solution, OR lemon Juice, mixed with water about 30% solution. Put this in a spray bottle and spray the area this will Kill it and stop it from coming back, if used regularly. Another great one is white vinegar mixed with water again about a 25% solution will do, and apply the same way, use a VERY fine mister bottle.
Also there are commercial products available, if you so desire,

Cleaning out mold is the easy part. keeping it from coming back is the hard part.
Any bathroom cleaner with a bleach solution in it should provide great assistance in cleaning mold.
to keep it from coming back you might try a paint primer oilbase with mold inhibiters in it.
I never had to try it inside an AC unit but we have used it successfully with some bathrooms and closets that insist on molding.

Hello,

Cleaning mold from your air conditioner is a simple process. However, it requires some special supplies. Before you begin cleaning your air conditioner, gather a vacuum cleaner, a long brush, de-greasing cleaner and cloths or rags. You will also need a container for waste. Follow these steps to clean the mold from your conditioner:
Step 1 – Remove the Plate Filter Using a screwdriver, remove the front plate filter from the air conditioner system. You may wish to clean the filter with dish or laundry detergent and water. Simply allow the filter to soak in a small pan of diluted detergent.
Step 2 – Remove the Plate Having removed the filter from the front of the plate on the air conditioner, proceed by removing the grill plate itself. Continue by removing any other metal coverings, exposing the inside of the central air conditioner.
Step 3 – Brush and Vacuum the Inside of the Air Conditioner Using your brush and rags, clean the dust from the inside of the air conditioner system. Ensure that you remove dirt from every crevice inside of the system. Be careful not to break the delicate pieces inside of the air conditioner.
Continue by de-greasing the inside of the air conditioner. Allow the de-greaser to stand for 15 to 20 minutes before gently washing the inner pieces with warm water. Ensure that water does not come in contact with any of the electrical workings.
Step 4 – Vacuum and Drain Excess Water Before returning the front plate and filter to the air conditioner, carefully vacuum the inside of the air conditioner system to remove any remaining dirt and mold spores. Using a cloth or towel, soak up any excess water that may be left over from the de-greasing portion of the cleaning procedure.
Step 5 – Reinstall the Plate and Test the System Carefully ensure that all pieces of the system are not bent or broken, and then reinstall the front plate. Test your air conditioner to ensure that it runs smoothly and without loud noises.
In order to best protect the quality of the air in your home, perform this mold cleaning procedure about once per year. This will not only serve to improve your overall health, but it will also prolong the life of your air conditioner considerably.

Take care.

Even if you think you had washed it thoroughly, you still can't be sure if you had removed all the molds. There might be just one tiny single spot left and it reproduces so it still grows and multiplies causing you and your family to acquire respiratory problems. It's good to see your physician as soon as possible and stop using your air conditioner in order to alleviate the symptoms. And better if you can replace it with a new one.


How To Get Rid Of Black Mold

Once you have completely finished inspecting your home and found even the smallest infestation of black mold growth, its time to begin ridding your home of it. Especially before it begins growing out of control and taking over your house!

Since most all mold reproduces with a combination of dampness and darkness, the first thing you should do to get rid of black mold is start drying out your home. This can be done with a dehumidifier unit that you can purchase affordably enough from any home supply store, or a major store such as Wal-Mart that sells these types of units.

symptoms black moldYou will be surprised at the amount of humidity in the air once you begin running a dehumidifier unit. The purpose of a dehumidifier is to **** natural moisture out of the air inside your home. Be sure that you empty the water collection bucket regularly as mold can grow within this as well if left unchecked for extended periods of time.

Having a dehumidifier is important especially if you run any type of air conditioning or heating unit regularly in your home and you can physically see moisture build up on your window panes. Window air conditioning units are good for this type of moisture build up excessively. So, if you use these, its a really great idea to pick up a dehumidifier.

Next Steps

While having a dehumidifier is step one in drying up your home, its also important to fix any water leaks around your home as well to prevent further mold build up and growth.

To further improve the quality of your home's air, you can consider purchasing an air filtration unit such as Ionic Breeze(tm). This will trap some of the pesky mold spores that travel through the air from outdoors into your home and stop some mold growth before it even starts. These units can be rather pricey, so be sure to shop around and find the best unit that fits into your budget and will get the air cleaning done.

Cleaning Black Mold

If you already have mold growth then this next step is very important to get rid of black mold and continuing to stop rampant mold developing. You will want to use a bleach-water solution mixture of 1 Part Chlorine Bleach to 10 Parts Water. This is roughly One-Half to Three-Fourths Cup of Bleach to 1 Gallon of Water.

You may also want to purchase some disposable cleaning supplies for this job as you won't want to hang on to them as they will become contaminated afterwards. So a pair of non-porous rubber gloves, a few dollar sponges and/or hand held scrubbers would be perfect, depending on where the mold is growing.

There is no need to leave the bleach-water solution set for any amount of time. Simply spray it on, wait for a duration of around 10 to 15 minutes, and then scrub the mold until the surface comes clean and clear of mold. You may want to leave the bleach solution set for a few minutes longer to loosen up those hard to scrub moldy areas before trying to re-clean and remove the mold.

This bleach-water solution can be used for wooden or rubber baseboards so long as there is no threat of your carpet being ruined from using it, or the wood being warped or otherwise damaged from the watery solution. If so, you can always lay down a plastic painting tarp on any areas you fear may be ruined by bleach. It can also be used for walls if necessary so long as the bleach will not ruin them. If you are going to be using the bleach-water solution on wooded areas, you may want to make use of large fans to dry the area more quickly after cleaning.

NEVER combine ammonia with bleach for any reason as this can create hazardous fumes by doing so. Only use bleach-water solutions and nothing else added to them to prevent further health issues.

Now, if you encounter mold underneath your household carpeting, furniture, or upolstery, you may want to consider completely removing any of these items. The reason being is that even with steam cleaning, it may not, and most likely will not, remove the mold spores. The best course of action is to remove the moldy materials, clean any other areas that were exposed to the moldy items, and then begin fresh with brand new materials.

Of course, this is going to be costly to replace, but necessary for complete mold removal if the infestation is there. However, if you have experienced flooding within your home, and catch it right away, you may be able to air dry your carpet and furnishings by using large fans to "blow dry" the areas and prevent mold growth from starting.

Another good combination is using detergent-water for cleaning hard floors and walls after flooding has occurred.

Once your home has been completely disinfected and mold removed, a great way to keep mold from coming back is to invest in a vacuum cleaner that features a HEPA filtration system within it. This will trap most of the mold spores before they have a chance to begin growing again in damp, warm, dark areas in your home.

Lg top loader has dirt or mold getting on clothes. What isit ?


Washing machines need to be cleaned regularly to remove mold from the tub area.
Run the machine on a hot cycle without clothing in, but add white vinegar to the tub as this will kill off any mold that is "growing" in the tub.
Do this every 2 to 3 months.

We have a very foul in our mobile home, and we think it is coming from our empire heater! is there anything we can do to fix this odor


Oder doesn't seem to be electrical smell or you would know a house fire may occur. We normally know the electrical smell I'm worrying you about, and if it is that, do not use it and call a professional! It may be mildew in the unit or in the ductwork. Mildew is quit common, mold is not. No one LEGALLY can tell you it's mold unleased certified by you state or province. Mildew can grow anywhere we have a warm surface that comes in contact with a cold surface. This means uninsulated ductwork, or aged ductwork. The unit itself can also produce some mildew due to lack of maintenance. And also, water can get inside the duct for many reasons if you have cooling. If water is trapped it can produce "growing" stuff and a smell. Varmints can also cause this, either by dying inside the unit/duct or by leaving their droppings, to say it nicely. Temporary fix is what we call in Texas a Odor Cake. These are sold at the HVAC parts houses. Come in a little Tupperware style cup, and are mainly used for fire, smoke, and mildew damage to a structure. You just set em inside the airflow and the help, but don't solve the issue. If mildew is present inside the unit, have a tech out to inspect/clean. And a ultraviolet light may be needed to help control the growth. Internet U.V. Light for HVAC to study on them. Hope this helps!

Towel mildew smell is being transferred from the washer. The washer must be cleaned first. The problem is not "brand specific" all clothes washers have mold growth to a certain degree. Bleach or vinegar will kill the mold inside your washer but won't remove it or the residue it grows on thereby making the situation worse because it leaves a "base" for more detergent to collect on and more mold will grow.

Washing machine mold / mildew odor is caused by:
#1 cause is overuse of detergents. Detergent companies are notorious for instructing to use too much detergent. Especially with soft water or when using liquid detergent no more than 1 tbsp of any detergent should be used.
#2 most common cause is using fabric softener because it's dispensed in the rinse cycle and will coat the inside of the outer tub with residue that is a food source for mold to grow.
#3 using only cold water for washing is fine but makes preventative maintenance very important. A weekly hot soak will dissolve odor-causing residue from inside your washer.
#4 not using the washer. If the clothes washer isn't used very often maintenance is especially important. If leaving for a vacation it's a good idea to clean your washer. Do a search to "remove washer odor" to read just how big the problem is. There are all natural washer cleaners that will also remove mildew odor from towels and clothing after the washer has been cleaned.

Mold inside unit


There is a product on the market that will prevent mold from growing in your air conditioner.You should be able to find it at a refrigeration supply house.Just take the product and place it in the area where the water collects.There is also a product to help you clean your unit of contaminants on the heat exchanger surfaces.It simply sprays on,and can be later rinsed off.Its usually a straight forward matter to remove the cover from an air conditioner.Usually no more than 4 screws.Some units will slide out of their covers,after removing the screws that keep them locked in place,and some covers simply lift off from the rest of the unit once the screws are removed.In either case the rest of the unit minus the cover will remain intact,and can be cleaned.Cleaning the unit will almost always make it work better too,so your killing two birds with one stone.

Mower has to be chocked to run


Oftentimes, this problem is the result of mowers left outside in ambient air that is high humidity. This, in turn, allows algae to grow inside the carb fuel float bowl and/or inside the fuel tank if left out for extended periods (one month or longer). Also the same thing will cause air filters to clog rapidly with mold and mildew - slowly at first, then more rapidly as the mold continues to grow. Get out the carb cleaner in spray cans and go through every ported passagewway in the carb body then reassemble using CLEAN screws, gaskets and all interrior parts. Any residue mold or mildew will continue to grow - and it can grow in gasoline!! Imagine that!!

Water draining from window air conditioner runs down the side of the house creating wet basement wall and mold grows inside basement. How to drain away from house?


If the inside is clean and the unit is installed with very minor slope toward the outside, you should not have any water draining. It should get picked up by the fan and blown thru the condenser (outside) coil, evaporating, and helping with the heat transfer. Take the unit out of the window. Take it outside, Remove the outer cover, and wash out the inside - especially the pan in the bottom and any slots where water runs from area to area. Try not to get the electrical control area very wet, if you do let it dry before re-assembly.
