Cat urine stain on Nubuck leather couch

[mdmerkey]

I have attached pictures so that you can see the left and right side of the two cushions - this is after the hyrdrator process. I also took a picture of the cushion with the t5 on it - it appears to have some residue on it from the cushion - is that good? the cushions stains still look so dark to me- am i still doing this correctly or have i somehow made it worse? please advise what i should do next... is the next step the fat liquor step?

[mdmerkey]

also the leather still seems to have a sour vinegar smell to it - is that normal?

It is good.

Better when the Towel-T5 is tight without any air space and the towel should be saturated and stretch as mentioned a few time to 'wick' foreign contamination through and trap by the towel.

Here are examples of how the towel is tightly placed.


#1
Product is spray to wet out the towel over the stain.



#2
It is brushed to removed air space



#3
It is tightly in placed without any air space.



#4
The paper shrink as it dries and tightens further as the leather dries.



#5
The towel is peeled together with the wick-up stains.

The darkening effect is the displaced chrome tanning agent that becomes a metallic stain and will need further treatment with d’Tarnish-1.3 after Fatliquor-5.0 as part of the drying process.


>>> please advise what i should do next... is the next step the fat liquor step?

Yes, it is.

Normal while still wet, eventually it will all be gone.

[mdmerkey]

so i don't need to do the hydrator step again - not sure i did it very well the first time.

No necessity to repeat if the leather is slightly wet about 25% before going into Fatliquor-5.0 step.

The reverse transfer may be used as the last wicking process after Fatliquor-5.0.

i have done the fat liquor process - do i let the cushions completely dry after this process? what do i do next - i do not have the tarnish product you described above...

>>> do i let the cushions completely dry after this process?

Apply the reverse transfer with Towel-T5 to it and let it completely dry.

Show some pictures if you are doing it right.
