Area Rug - Mold/mildew damage. Cant remove

[OfflakeTony]

We are a Vacation Rental company who is planning on doing our own carpets/rugs. Just got our equipment/chemicals and have practiced on commercial carpet in the office (machine/chems worked really well and place smells great/carpet looks great).

***STUPID MISTAKE***
After typing this, I decided to go see what the material is, the rug is 100% wool pile from India, don't rely on what your inspectors say the rug is made of.
The rug doesn't look worse than when we started (actually some of it looks better) but we will hold off until we figure this stuff out a bit better/someone tells us our mistake was stupid and how to properly do this/what chemicals and processes to do.
***STUPID MISTAKE***

We are using a Prospector PE5003 extractor with heat (From https://shop.truckmountforums.com). Tried up to 300PSI.
We have started our first job which has been our priority since getting this machine, a very large/expensive (white/light color) area rug that had water sit on it for a few days. The rug has what I can only describe as mold/mildew stains that we have not been able to get out. We used TMF black label/agitated the carpet. That didn't work so we tried Dry Slurry from https://shop.truckmountforums.com. We tried hand scrubbing with a really stiff brush too. Neither chemical has pulled up the mold/mildew stains. We did pull a red wine stain out of the carpet (about 90/95% of the way) though. Before I go trying more chemicals/buy more things, I wanted to check here and see if anyone has any suggestions for what to do.

Are you saying that the Rug that has water damage is the Wool rug you first talked about?
If the rug is Wool you will have better results in using an Acidic rinse and not an Alkaline (Dry Slurry).
In dealing with wool you need to keep the PH low. I would use Prochem's All Fiber Rinse. This product has a fresh scent unlike some acidic rinses that smell really bad after applied.
To clean it : Use air mover to speed dry. Use the Acidic rinse then extract if discoloration still remains try in a small area (a quality oxidizer for browning). Some pet odor treatments have oxidizers for the stain so you can use these in a pinch. When using an oxidizer you will see almost within the first minute a change.
Remember oxidizers can be used with wool but in moderation. More is not better. Mist application recommended.

If you use an oxidizer speed dry the rug first then apply, groom in then leave it alone. Don not speed dry.
Hope this helps.

I had a similar rug with a raised pattern in my house; after a few unsuccessful attempts to clean it, I took it outside, cut it up, and placed it on the curb for a WM. In your pick, I'm seeing heavy browning, I'd mix some fine fabric shampoo
( Prochem), lightly brush the raised pattern and rinse it with an acidic treatment of your choice( I use Axiom free rinse) if that won't help, go with a browning treatment( 3-5 ph) I'm using Multisteam Formula D, it's suitable for a fine fabric and wool, read the direction. I bet twenty bucks that would fix your problem. You can use sea sponge or horse hair brush to apply shampoo or rinse, looks like light spray only wouldn't be helpful in this case, forget any
hard brush.
Let us know about your progress.

Wool rugs are absolute beauty for a house. Don't use a stiff brush to clean your area rug. Scrub the rug gently with a mild carpet cleaning solution. Otherwise, it’s recommended to have wool area rugs professionally dry-cleaned for stubborn stains.
