Any advice on getting the yellow pet urine stains out of carpet? Any advice will help. I can lighten it but it doesn’t come totally out.

Afraid to say I might not know the complete and technical answer or maybe I just haven't come across serious enough urine stains..

But, some TMF Black Label, little Pros Grade Citrus Solvent, and some Unchained seem to get rid of nearly everything..

I think the technical answer might be using a peroxide based solution or oxidizer..

Thank you! I’ve been using the spiked pre spray and like I said, it lightens it but doesn’t remove it. I was going to try the unchained by TMF but wanted to ask around and see what I could learn.

Some of them will be permanent especially on nylon. However, a good peroxide stain remover is the most effective way to remove them if it's humanly possible. These almost always need to be sprayed on last step and left to work for the best results. There are some other things I could suggest, but this is the most important one and I think the one most used and most effective.I'm doing a job tomorrow where there is severe yellow stains in one bedroom. I'm almost 100% certain that nothing on earth will remove them. I think the damage is permanent. I will still do my best because I informed the customer and she still wants me to try so I will.

Thank you!
Do you have any pictures or more info? Sometimes little nuances matter. Was the urine coming from the dog being on antibiotics, how big is the stain , did you use spot lifter to eliminate stain, does the padding have a moisture barrier and such. We've been talking about mitigating urine salts on many occasions and there are so many ways how to deal with it, from OSR and bucket method ( the most effective for some members) trough UPT- Pro's Choice or using stain remover
( peroxide based - I prefer Prochem)which might require additional visit after application, covering it overnight and revisit it next day and rinse it out. I carry minimum of 5 products for urine treatment, that includes Odorx, Unleashed , Pro's Choice Os-1, which is also great for old blood spots and Odorcide , formula 210, which works great for smaller areas . Spray liberally on dry carpet, roll it in and repeat if needed. That's done in case when customer is not open to idea of pulling out carpeting and removing padding... it has nothing to do with taking out stains.

I will add this if anyone is interested. On very rare occasions, I found that a 2 part stain remover could remove some urine stains that a single part peroxide couldn't remove. If I have a lot of urine stains I will either pretreat them all before starting the job with something like Matrix Bad Dog or another strong peroxide and only post-treat those that weren't removed. On nylon or wool, the chances of it being permanent are far more likely so the customer is informed before any work is done. Under-promise and over-deliver. It's great when you can remove them all, but that just doesn't happen all the time in the real world. Most of the urine jobs I've done over the years didn't have permanent staining and many didn't require any actual stain removers.

Yeah it really is a crapshoot, I had a house a few days ago, yellow stains in every room. I mixed up a heavy peroxide pre-spray by spiking with sodium percarbonate like wandwizard stated, some of the stains popped right out, some didn't pop at all.

There are too many factors at play.
