ok so you guys stance on browning when it occurs on synthetic fibers is that its wicking soil, if that is the case then why often times on an olefin berber that has had water damage, that often I can merely mist it with an acidic product and remove it??
I wouldn't say merely mist it. Alot of times synthetics will mimic browning when there is an abundance of moisture left in the carpet. Any soil deep down in the pile and even beneath the backing and in the pad such as construction dust, fillers in the latex breaking down or an assortment of deep down dirt gets brought up during the drying process. In your case, the water damage has saturated the pad and carpet much like a careless cleaner. Any soil in the carpet and pad can be brought to the surface. There are several ways to mitigate the problem. Also any minerals in the water allbeit the water damage source or just plain moisture if its a harder water, could cause the "browing" as well.
Clean or Reclean it and force dry the carpet with several fans and lots of dry passes during extraction.
And post pad the area to get the carpet as dry as quick as possible.
Or you can opt for a low moisture method if the carpet has already been cleaned and dried. Use your favorite encap shampoo and either bonnet clean it, pad encap it, or straight encapsulation being careful to not cause friction burns in olefin.
Or as you mentioned, you could try the misting acid rinse but it probably is not a result of a pH inbalance and so an acid rinse is most likley not going to remove the wicked up soil and spots. I've heard that Ricky G's new shampoo EncapHydroxy is great for these issues.
Otherwise, the browning on the white couch if it is cotton or a cellulosic fiber, is best explained by Jose Smith.
