Hi, I wonder if you guys could help me. During the summer I used a mould spray on upvc windows which contained anionic surfactants with chlorine bleaching agents. I rinsed this off but it left a white film on the glass and so I used a household cleaner called Flash which has < 5 % Non-ionic surfactants, soap,Glutaral, Benzisothiazlinone, Perfume and Limonine. I also used the mould spray on plaster around the window frame and on the silicone mastic around the window frame. I rinsed this off with plain water and when it was dry I applied a PVA (acetate) sealer to the plaster around the window and along the mastic. A couple of weeks ago I went away for a few days and upon my return there was a very strong chemical smell in the rooms where I had used these products. It was so bad that the next day I rinsed all the windows again twice with plain water and then once with a bit of flash diluted in half a bucket of water and then rinsed everything again with plain water. I was affected by this as I had trouble breathing and had a burning sensation on my skin. I think I may have caused Chloramine gas as a result of the reaction of chemicals and would be grateful if you would be able to tell me what I can used to neutralize this as I have had to move out of my property as the fumes are affecting my health. I have been in touch with the manufacturers of the mould spray but they say there is no remedy to neutralize this reaction between these chemicals. I would be very grateful if you could help me to resolve this problem. Thank you. Tess.
