I have an older gentleman client that is incontinent and there are some places throughout his apartment where he has had accidents. I normally use HWE and Waterclaw on these spots with some Unchained. It works ok but I do see some people claiming cold water is better than hot on urine. Do any of you guys use cold water or know of any better methods?

If the urine is relatively fresh, you could can use cool or lukewarm water.

If you are using Unchained or other peroxide based treatments, very high temperatures could cause color loss when they react with the product. This is also possible with sodium chlorate based solutions (often called "chlorine dioxide").

You are at the most risk with wool (pretty unlikely in an apartment) or nylon (more likely if the carpet is old).

I'm pretty sure that odor is more of a concern at this point than dyefastness. Are you being payed by the landlord or by the tenant?

Tennant. It's Poly carpet, and you're right odor is the main concern. So far it's working ok but not perfect so I'm interested in what others are doing in similar situations.

You'll get plenty of good advice here.

With human urine, there is a great deal of volume of liquid involved, and thus far deeper penetration into carpet cushion and the subfloor.

I find the issue involved is less the product being used than making sure that the product that you choose to use reaches everywhere the urine has.

Frankly, if there are repeated urine intrusions from an adult human, it really should be time to consider replacing the carpet and cushion.

I clean f0r an elderly gentleman who has bladder issues about every 3 months. Carpet, tile, LVT, and upholstery on that job. The hotter the better when it comes to odor removal. I know it's impossible to kill all the bacteria, but killing some of it is better than none. This place is rank when I get there, and the odor is mostly gone when I leave.

So I'm voting for hot is better than cold. And mixing up sodium per carbonate in with the treatment with hot water is always good

Well, not really any to add on what/ how,

but , finding the specific areas, use a black light, ? or just hammer the whole place?
Wondering if much different than a pet? I know black lights are limited when looking for it on polys, and olefins., as it does not bind to the fiber and tends to run down into back, and pad.
