I'm sorry to hijack the thread, but I just looked at a white cotton couch with browning & yellowing, has been in storage 2yrs+. I do have some 40vol, would yous guys recommend it for this?
Thanks
Absolutely use the Haitian Cotton Shampoo. Do as Steve said. This should correct the browning and might get rid of the yellowing. Might.
If the HCS does not get rid of the yellowing then do this...spray with brown bottle hydrogen peroxide or maybe 20 volume....then put the piece in the sun if you can.
