Thanks tuscarora dave! I just got back from taking this customer her car back and she was excited to see her interior and mats cleaned. She had already thought that she was going to have to buy new mats.
This is good advice on cleaning the red stain from floor mats. It turns out this was Hawaiian Punch. I followed Dave's advice and it took about 8 times of following this process, but it was worth it. I just stopped in the middle of my detailing every 10 minutes or so and scrubbed, steamed and put back in the clear ammonia. It appeared the stain was out however, if you looked real close, you could see a faint spot once they dried.
There was also some of this stain on the carpet next to where the mat was. I thought this process might work on it as well, so I soaked a sponge with the ammonia and set it on top of the stain. After a few minutes, I laid the wet towel on the spot and applied the steam iron. I ran out of time before I got all of the stain completely out but I'm convinced if I had more time, I could have got it out as well.
I told her if she wanted me to finish getting out the small spot, she could just call me and I would come back and finish. She said it was fine like it is. I don't do this as a full time business so I don't have all the steamers and other equipment you professionals have. I do, nonetheless, want to do the best job I can.
Thanks again Dave for your advice. I hope I can help someone else along the way. You have seen the before pics so below is the after picture. It may not be perfect but it is surely an improvement. The most important detail is the customer was happy!
