Cat urine stain on Nubuck leather couch

[mdmerkey]

The cushions are looking better - there are still some dark spots but not too bad. What is the next step?

[Roger Koh]

May need some touch-up re-clean, please show what products you have remain that can be make good used of.

Beside appearance, is there any smell like, sour, ammonic, putrid?

Does the stain area feels as soft as the surrounding areas?

[mdmerkey]

I will take a picture of the products we have left when i get home. There is no ammonic smell but there is a little bit of a sour leather smell but it does not smell like cat urine. The leather does not feel exactly like the surrounding areas but it is much better. We have to do the protector step yet - which i assume is the last step.

[mdmerkey]

Here is what i have of the following chemicals:
Hydrator 3.3 - a small portion at the bottom (not much at all)
D'Urine 2.1 - little less than 3/4 of a bottle
Fat Liquor - 3/4 of a bottle
Acidifier - 3/4 of a bottle
Rinse 3.0 - 1/2 of a bottle
d'Protein 10 - 3/4 of a bottle
Protector S - have not used any of that yet

[Roger Koh]

>>> There is no ammonic smell

The d’Urine-2.1 has done its job!



>>> but there is a little bit of a sour leather smell but it does not smell like cat urine.

The d’Urine-2.1 is still present and will eventually dissipate, this products neutralizes the ammonia and alkaline phosphorus salt found in urine that characterize the smell.



>>> The leather does not feel exactly like the surrounding areas but it is much better.

Not sufficient fatliquor is the reason – may repeat the Hydrator-3.3 > Fatliquor.LS-5.5 system
Do you like the "leather-scent"? (your comment please)



>>> We have to do the protector step yet - which i assume is the last step.

Do not do this step yet if there is a desire to repeat the decontamination and the leather rejuvenating process.



>>> Here is what i have of the following chemicals:


>>> Hydrator-3.3 - a small portion at the bottom (not much at all)

Finish the Hydrator-3.3 to those areas as REPEAT STEP-3



>>> d'Urine-2.1 - little less than 3/4 of a bottle

Job done!



>>> Fatliquor.LS-5.5 - 3/4 of a bottle

This is the reason why “the leather does not feel exactly like the surrounding areas”
Repeat and soak up the leather will soften up the leather tremendously to those areas as REPEAT STEP-4



>>> Acidifier-2.0 - 3/4 of a bottle

Use this remainder to wet the stain out, cover with Towel-T5 and let the stain wick through the towel to be peeled off – as REPEAT STEP-1



>>> Rinse 3.0 - 1/2 of a bottle

Use this remainder to wet the stain out, cover with Towel-T5 and let the stain wick through the towel to be peeled off – as REPEAT STEP-2



>>> d'Protein 10 - 3/4 of a bottle

Job done!



>>> Protector S - have not used any of that yet

Wait until appearance and tactile-feel is satisfactory to the end of the entire process.



Please show pictures of the recommended REPEAT that you are doing it right!

I have done the acidifier step again as shown in the picture. I will go through each step after the cushions completely dry - i will go on to the next step. And yes in answer to your question i don't mind the leather smell.

Towel-T5 that comes with the kit is a flat texture and stretchable paper towel that works with horsehair-Brush-1
It can be washed, rinse, let dry, iron flat and reused.
Otherwise an equivalent flat texture for better surface contact preferred.
