The carpets are 3 and 5 years old, and none have rubber backing. At first I thought it was the white carpet, and they even replaced it. Then when I scrubbed my green rugs and the water was yellow I saw that was not the problem. I do have natural gas but in the basement were the furnace is nothing is yellow and the carpet down there is not yellow. The walls and the ceilings do not turn yellow. The house is very well insulated. I have very high ceilings and in the winter my heating bills are like nothing. No one in the house has any trouble breathing of has had any trouble breathing. I live by a ford stamping plant, but I'm not sure if they burn anything. I was thinking could it maybe be the stuff you sprinkle on your rugs before you vacuum-like carpet fresh? Also I have used electric potpourri pots with liquid potpourri for years. I threw all on them out, and I am not going to use them ever again. On my fireplace where I had a potpourri pot its yellow. So maybe this is the problem. Any one use these pots with liquid potpourri? Thank you all for all the input and feedback. It is really helping me. Thanks so much. ... View related article.
Oh also no one smokes in my house. And it is not stains from a pet. When I had my vents cleaned I asked them about it, and they looked at me like I was crazy. I went over a spot on that rug over 20 times and it looked clean. Until the next day that is. I am going to replace that carpet because I don't want to spends days or even weeks scrubbing it. I was thinking maybe it could be my carpets? I will soon know when I buy a new rug from a different place. Any advice? Thanks you all for your input. ... View related article.
