Cat urine stain on Nubuck leather couch

[Roger Koh]

>>> The two worst stains smell slightly sour

Let the leather completely dry and the sour odor goes away, show some pictures and we will go from there to improve on the appearance.

The pictures i posted above are what the cushions currently look like.

When the leather is completely dry, the 'dry process' would be:

1st. Use the nubuck Brush-2 and brush to remove surface residue and extend to the entire cushion.

2nd. Repeat with Eraser-4.

Please show the result.

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?

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.

Here is what i have of the following chemicals:
Hydrator 3.3 - a small portion at the bottom (not much at all)

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
