Pamela on Aug 24, 2013I would use bleach in a spray bottle and unfortunately do it by hand that way you can control the bleach getting on the floor. I would still put down drop cloths which are cheap, which would protect the floor even more. My suggestion would be to put a fan into the room every so often to circulate the air and dry the ceiling if it is collecting moisture. Good luck.Helpful Reply

Jim McGovern on Aug 24, 2013Thank you Pamela. That's basically how I cleaned it the first time. The only exception was that I used a stiff bristled brush. I just did the outside edge and used a hand scrub brush and it came out pretty well. The cleaner I used was Simple Green. I think I'll try a spot and see how it comes out.Helpful Reply

Woodbridge Environmental Tiptophouse.com on Aug 24, 2013Power washer should remove this. If it did not, the pressure was not high enough. If your thinking moisture is causing this to occur, then painting it will only be a short term method of making it look good. Vinyl which I think this is, does not support mold development. its the dust and soils on the surface that does. Once painted even with a microbial additive in the paint, you have effectively provided a organic material that mold will grow on even faster. You may need to simply use a strong solution of detergent and a stiff scrub brush on the surface. Bleach does not remove mold. It simply removes the color making it appear that its gone. While it may physically remove some molds, and that is simply because it washes them away much like a strong detergent does, it hardly kills a lot of the molds found today. Bleach that is strong enough to remove and kill mold is not sold over the counter. Regardless of what you decide to do, you need to determine the cause of the moisture and attempt to correct this issue. If you do not, what ever it is that is growing on the surface will return.Helpful Reply

Donna J on Aug 24, 2013I had that same problem with my patio ceiling earlier in the spring. I used a bleach solution and a mop and went over the entire ceiling. It cleaned the ceiling very well so the mold was not visible. However, as of today I need to clean it again. I know the problem is with my patio roof. The contractor skimped on the roof lining and now the water is coming through to the plywood. For now I know I will have to clean my ceiling ever so often until I can replace the entire roof. Good luck with your project.Helpful Reply

Jim McGovern on Aug 25, 2013Thank you all for the comments. I checked the ceiling this am and it was covered with moisture. My ceiling is all metal. It was installed in pieces approximately 10' by 18". I think when they connected the strips they did not seal/caulk them and allows moisture to come through when it rains. We have a lot of dew on the grass every morning so I'm thinking the moisture in the air is causing me problems.Helpful Reply

Louise F on Aug 25, 2013@ @Jim McGovern i am so grateful for your question. i had my roof replaced three years ago and also had a screened in porch built at the same time. Presently the ceiling is just like the one pictured. Actually i did not have a ceiling put in. Just left open and painted white. i am just sick about the way it looks. But at least now i have some options. The thing i am concerned about, though, is: Is the roof leaking or is it just condensation? What to do?Helpful Reply

Louise F on Aug 25, 2013i just read the Woodbridge comment. Looks like i will have to clean with some kind of mold killer to get rid of the mold, then use something like Kilz before i actually paint. O Goodness, what a mess.Helpful Reply

Jim McGovern on Aug 25, 2013There is a lot more to my screenroom problems. The gutter they installed is useless. I noticed when it rained that a waterfall was coming off my roof. Never got into it until recently. The roof completely coved the top of the gutter and no water could go into it. I had to take my jigsaw and cut out a hole in each panel. The bad result of this is that my septic tank is about 10 ' away and all the water goes into the ground and fills the tank. That stops the flushing of the toilets. Glad I'm retired and don't have anything else to do.Helpful Reply

Natalie Carroll on Aug 25, 2013I just talked to my hubby and since we also have a septic tank in our yard we can understand the problem of it being full....so he is strongly suggesting that you find a local handyman to install a good working rain gutter to channel the water away from the septic tank so that you are able to use the toilets, etc in your home.Helpful Reply

Carole on Aug 25, 2013If you are going to use bleach and are working overhead, please ensure to wear safety goggles to protect your eyes. I would also try to get to the bottom of what is causing this mould as it is a big job to keep it clean and or paint it frequently. Any leaks or moisture getting in, the problem needs to be fixed at the root cause.Helpful Reply

Woodbridge Environmental Tiptophouse.com on Aug 25, 2013Jim if the ground water is filling your septic system then its faulty. NO rain should be able to enter into it. The tank is supposed to be solid with only openings for sewage to enter into it and an exit for effluent to go out to the field. If water is entering it that is more important to fix then some moldy ceilings.Helpful Reply

Jeanette S on Aug 26, 2013Bleach on metal? I thought bleach ruins metal? I have wrought Iron railings on the front of my house painted white and when I clean them with 409 they seem to have a stain like yours. I just clean them the best I can...hubby touches up on any rust spots and I let it go. No one inspects the railings when they come over so I do not bother with it!Helpful Reply

Pam Townsend Bies on Aug 26, 2013I live in Florida and understand this problem all to well. My metal ceilings have the same problem. Humidity causes mildew and you just need to add it to your to do list once a year. I tried everything for years and FINALLY found that chlorine mixed with water in a regular 1 gallon pump sprayer works very well for large outdoor applications. It does not take much, I use about a cup of chlorine to a gallon of water. Use common sense precautions. Open windows, wear eye protection etc. I stand back and let the pressure sprayer do the reaching for me, spraying up and at an angle. I also use a hand sprayer in my sun porch with a rag. I understand the flooring issue...you may want to cover it with plastic. It will kill plants. You can also use a long handled scrub brush and watch the black melt away. rinse with water. As for painting it, I would not, you may find you will have a larger mess than you first started with and cleaning will not be as easy. I have some metal awnings, my next project is to repaint them using an enamel appliance spray paint. This also works very well for making your AC vents look brand new! Hope this helps.Helpful Reply

Melissa on Aug 26, 2013Bleach is not recommended for aluminum gutters, siding, or ceiling material. It can strip the color finish and leave the shiny metal visible. At my work we recommend the following solution to clean: 1/3 cup of liquid tide or similar detergent per gallon of water. The solution should be applied to the soiled area by means of a soft rag, sponge, or soft bristle brush with a gentle rubbing action. Do not rub vigorously so as to create glossy areas over the satin finish. Always thoroughly rinse with fresh water after cleaning.Helpful Reply

GrandmaCarol Speight on Aug 26, 2013I have operated my own cleaning business for a number of years and have found,(altho very labour/labor intensive)...that good old fashioned hot water and soap works wonderfully on mold/mould. There is also a bio-degradable product out there and widely available in the United States called "Mean Green". They have one they suggest is good for your problem. Personally I like the soap & water idea......no bleach!Helpful Reply

KMS Woodworks on Aug 26, 2013The paint on the metal is most likely a Baked on type of enamel..which is pretty durable I would revisit the power wash route...and be a bit more aggressive. If it is not working too well you can use a "deck scrubbing broom" and then more washing. I second woodbridge's comment about the septic...something is amiss there and should be adressed ASAP.Helpful Reply

Deck Care PLus on Aug 26, 2013Never use straight bleach. Mix about a gallon water with about a 1/4-1/2 cup of bleach and add some dawn dish soap. Spray on and let sit. When black spots turn light brown mop or scrub off.Helpful Reply

Virginia on Aug 26, 2013Bleach doesn't kill mold it just removes it for "now". You need moldex. I also heard borax kills mold. Since you don't want to spray.... I guess you'll have to use a mop (the squeeze out type) so it won't drip on you and moldex it. The mop won't keep after you put this chemical on it, but you can get them at the dollar store.Helpful Reply

Woodbridge Environmental Tiptophouse.com on Aug 26, 2013I know this has been a crazy year weather wise. Some are in severe droughts and others such as you are being flooded. My suggestion is if your planning on adding more soil to help with run off and such, that you consult with a septic person first. There is a lot of engineering that goes into septic fields and depth of leach field is one of these factors. By adding additional soil you may disrupt the way the field operates. Although I doubt you will be putting that much soil down, It is always best to consult with someone familiar with your area and system just in case you end up doing something that may end up costing you more then it is worth. The few dollars if they charge anything at all is well worth knowing exactly what you can and cannot do to move this water from the leach field and the holding tank(s)Helpful Reply

Jim McGovern on Aug 27, 2013I will be adding very little soil. Actually the area of the drainfield does not get a lot of standing water. I will not be adding dirt that that area. I have taken pictures after a rain storm and will use them to determine the area to add soil so the water will run off. A lot of these areas are near my French Drain. I layed out the FD area to be able to collect that water. After working on this project for some time I really feel runoff from the screen room has been my main problem. We've had some real good storms since I worked on the roof and installed the French Drain, and have not had any problems. Thank you very much for your input. It has been very helpful and makes me think a little deeper.Helpful Reply

TheDIYGirl on Aug 29, 2013I don't know if anyone has mentioned it so far, but I had a second floor deck that had white opaque stain on both the top and bottom. The underside (on the ground level) would get black mildew all over it. While I don't like to use this stuff often, I found TSP (trisodium phosphate) worked better than anything else. Mix it up in a garden sprayer, spray the ceiling, let it sit for 10-15 minutes, then power wash and it should be sparkling white.Helpful Reply

Jim McGovern on Aug 29, 2013I've posed an alternative to my wife and she like the idea. The house is gray, and I'm thinking about painting the ceiling with gray enamel. I've completed the repairs on the cutter, caulked where it connects to the ceiling and primed the area with Kilz. I'll paint the gutter and the outside ceiling with white enamel. I'm thinking the color gray will hide more than a white ceiling.Helpful Reply

Valerie on Sep 09, 2013Try using a teaspoon of oil of cloves mixed in a spray bottle, together with a liter of water. Spray the area, leave overnight, and 'wash down' the following day using a broom with pantihose pulled over the bristles.
