Hey all, looking for some help with a polyester rug. Being fairly new to carpet cleaning I’m hoping this can be corrected.

Customer said the rugs were in a flood. My tech took them to the shop and cleaned them with the truck mount using a crazy high PH pre spray. Rugs looked good but the next morning they’re brown. I’m sure it probably had to do with the high ph but im
It sure how to correct it. Cannot be corrected? Any advice would be greatly appreciated

Here are some pics … the rugs were pretty brown when he started … then they looked pretty good when he was done… then the morning after

Run an acidic rinse or spray acid rinse all over it, extract and get it dry as possible. Thick poly rugs take forever to dry.

Sorry I missed this until now! I've had rugs, especially thicker rugs, that held a lot of soiling towards the base of the fibers. In flood situations this can be particularly common as the water can carry soiling from wherever it travels into the rug. As the top of the fibers dry faster than the base some soil can be drawn up to the top as it dries.
In my experience the best way to remove as much soiling as possible is by immersion cleaning. That said, at this point you may get acceptable results with a vlm method to clean up the top of the fibers without getting it too wet.
Of course this is just one scenario I've seen, the issue could be more chemical than soiling and an acid rinse may help. Either way controlled wetting and fast drying are your friends.

If it’s just wick back soiling reclean it and dry it with blower fans pointed under and over the rug…….floating it. If it’s actual browning run an acid or browning remover then float it with fans……it was wet way to long. Also if it’s clean and just browned out wet down a bonnet with an acid and buff it is another option.
