How to remove the “new carpet smell” (VOCs) from new carpet

Sorry to hear about your stain, but here are two options.

Tea should be fairly easy to remove. You can try blotting it out with very hot water and an absorbent cloth, or borrow a carpet cleaning steam machine and give it a try. Another option would be to hire a commercial carpet cleaning service. I use this type of service all the time in the apartments I manage. In this area it only costs me about $80 per room and the results are amazing. If you talk with a cleaning service, they can tell you if your stain can be removed before you hire them. Some will guarantee that the stain will be gone. This option is certainly a lot cheaper than paying to replace the entire carpet and padding. Good Luck.

If your carpet is a light color then try white vinegar on it first. I use this for pet stains and its light years beyond any product specifically formulated for stains and 1/20th the cost. It kills germs/bacteria/mold. I pour the vinegar straight from the bottle onto the stain, thoroughly soaking the carpet. It will begin to react with the stain and start fizzing. Once the fizzing stops you can soak it up with a paper towel but its best if you use a steam cleaner with just water in the tank to remove as much of the vinegar and the residual odor as possible. It will have a strong odor that will completely dissipate after two days assuming you sucked enough of it up after application.
