White things have black film in my house?

[millertime150]

I noticed that sometimes white objects such as toilet seats and white plastic turn a blackish tint in my house. It can be cleaned off ususally without much effort. We don't smoke, change are filters regulary, and light candles for only several hours a month.

Any ideas?

I just don't want to breath in anything harmful.

I'm wondering if it might not be soot from your heater.

[Strikermike]

It could be related to your furnace, or boiler. What kind of heat do you have in your house?

Also, how long has it been since you replaced your filter?

[RichGem]

What the others said. Also to consider, particularly if found only in damper environments, must and/or mildew.

2 months ago I replaced it.

I have gas heat and the furnace is in the attic

Any factories or industrial facilities nearby?

[Strikermike]

Gas does not usually produce a black soot. How old is the furnace? Look at the feed registers. Do they have the black film on them? If not the problem probably lies elsewhere.

Your air ducts probably need cleaning.

About the heater: If you really are getting soot from the furnace then that is a strong indicator that the manifold is cracked and allowing the combustion gasses into the house. The real danger there is carbon monoxide poisoning. Gas furnaces are designed to vent all of the combustion gasses out of the house.

Excellent point.

That is very true. But we don't presently know that it is soot. We need more info. He should install some CO detectors, and probably have the heat exchanger checked for cracks.

Ok, this is a weird topic to bring up, lol.

That said...is there any construction going on anywhere (within a few blocks) of your home, or any neighbors doing any sort of renovations?

[tg16]

I would also check to see if your neighbors are experiencing the same.

+1, if you don't already have them, get some carbon monoxide detectors.

I'm amazed. :blink: Symptom: black film on stuff. Diagnosis: Cracked manifold in furnace.

And bingo! Only on B&B! :lol:

You have to love this place. :thumbup:

[millertime150]

I have some Carbon Monoxide detectors already. Maybe I will buy some more.

Ducts probably do need to be cleaned.

No construction or renovations in the area.

Gremlins? Aliens? Chupacabra? Fallout?

[Gruder]

Sleep painting. (Likely with watercolors.)

But seriously, I'd go with the duct cleaning. How long have you had the house?

In one of my houses, I had the blackest dust, I had ever seen. If I dusted with a papertowel or white rag, it looked like carbon was being wiped off. I regurally changed my furnace filters, no exhaust leaks in gas appliances etc. I finally had the AC ducts cleaned and solved my problem.

Well, if it had been them, you would see much larger brown splatters everywhere, not mysterious black dust...they are notorious poo-flingers. :lol:

If you have any poo, fling it now.

Who flung Poo?

No, I prefer General Tao Chicken.
