Im thinking it is ink have you tried your ink removal strategy?

I will try treating it as ink. These are the steps that they listed on CTI's website:

FOR CARPET:

Step 1. Apply Pro Solve to ink deposit.
Step 2. Agitate gently but thoroughly until deposit is dissolved.
Step 3. Apply Power Gel to deposit and agitate.
Step 4. Thoroughly hot water extraction rinse.

Tip: If stain remains apply Stain Magic, cover with damp towel and steam heat for 15 seconds.

Is this the way you'd handle it?

Thank you.

I have found that the best thing to do is:
Use only the smallest stain to test on.
Wet a small area of clean cotton cloth with ink remover
blot area very gently, you will be able to tell if there is ink
on the towel if it will come out.
There are so many different inks on the market that a lot of
times removing 100% of the spot is impossible...RR
