Hello!

I have been doing a lot of research on what to get for my couch my dog's friend peed on it it only hit the sides between the cushions which isn't too bad but the leathers definitely dried out a little bit.

We have this sofa in the sienna color

The underside of the cushion is fabric it is not leather on both sides so any help will be great and I also want to keep the couch in good condition.

Thank you,
Saranii Muller

Hi roger,
Before finding your products I tried some damage control of my own with saddle soap.

So this is the result.

>>> I have had the products for some weeks but have not had a chance to do anything with them. What is the recommended sequence for using the products to fix the seat cushions please let me know thank you

Here is the product description and instruction. . .

Product Description
Leather DoctorŽ Kit-L5.uk urine killer kit is specially developed to decontaminate urine problems for most smooth leathers. Aged urine is detectable with its characteristic ammonic odor. The presence of ammonic odor may indicate the shifting of pH value up to 10. The leather will most likely feel sticky or slimy when wet finger testing it. This sticky feeling is a sign of leather denaturing and reverting to rawhide. Stabilizing this sticky phenomenon is done with pre cleaning with CleanPro-1.5 follows with Acidifier-2.0. KillUrine-1.2 treatment to neutralize the urine turning ammonic begins and it let to soak in contact for chemical reaction to take place and is very noticeable with a strong sour odor. This odor diminishes as it slowly evaporates. At this stage, the leather should feel squeaky after returning to its chemistry integrity of pH 3 - 5. Stiff leather is relaxed and sticks together fiber separated by Hydrator-3.3. The penetrated stain removing process continues with hydrating until complete satisfaction during a dry inspection prior to fat and oil replenishing with leather scented Fatliquor LS-5.5.In severe cases color refinishing is the last resort for a pleasing appearance. Note that the mentioned products suffix numbers denotes its pH value in this holistic approach for perforated-leather urine decontamination process.

Instruction

Restoration Cleaning - 1. Surface contamination is towel extracted and remaining soiling is removed with CleanPro-1.5 (pH 1.5) in conjunction with detailing horsehair Brush-1 and terry towel extraction until towel shows clean. The remaining residue is further rinse off with Acidifier-2.0 (pH 2.0) in conjunction with Brush-1 and towel extraction until towel shows clean. Leather surface is detected for any tackiness and should return to a healthy squeaky feel once the leather is pH balanced.

Urine Treatment - 1 Apply KillUrine-2.1 and let it soak until natural dry. Sour odor will dessipate once it evaporates completely.

Hydrating - 1- Hydrator-3.3 is applied to soak into the leather to relax stiff and stick together fibers and to wick out suspended foreign contamination. 2- Wrapping the leather with paper towel and wet it out with Hydrator-3.3 is an advance technique to let the leather soak up the hydrator for slow ansorbent leathers. 3- The paper towel is left on the leather to dry naturally; this technique allows the wick soiling particulates to be trapped by the paper towel instead of remaining on the leather surface.

Fat and Oil Replenishing - 1- Fatliquor LS-5.5 is applied and distributed with a foam brush until the leather is saturated. 2- Continuous second or third application is repeated each round the water contents evaporates until saturation. 3- Leave the leather natural drying for extra softness.

Rub-Resistant Protection - 1- Protector-B+ is applied by mist spray and spread with paper towel. 2- For routine application, a paper towel is recommended to extract soiling simultaneously.

So I follow these in that order?

>>> So I follow these in that order?

Sequence of urine decontamination process is correct, optional appearance correction is done after Fatliquor-5.0.

You may show some pictures as you go along if you are doing it correctly.

Example the Hydrator-3.3 details can be found in from this link:
http://www.leatherdoctor.com/hydrator-3-3/

Fatliquor-5.0 details from this link:
http://www.leatherdoctor.com/hydrator-3-3/

This urine de-contamination does not take care of appearances. After Fatliquor-5.0 the appearance is inspected and oxidized darkening effect from the chome-tanning may be reduced with CleanTarnish-1.3 > Basisfier-8.8 system.

http://www.leatherdoctor.com/basifier-8-8/

Color restoration is the last resort for color appearance.

Protector-B is used only when color appearance is satisfactorily restored as the final process.

For your reading, urine is time sensitive and the longer the wait the more damages the leather gets from denaturing or reverting back to rawhide. The leather beomes more tacky as it denatures.

For your reading...

Urine: Urine is a compound waste discharge, comprises of urochrome, uric acid and the ammonium salt to deal with. When deposited urine attracts the natural bacteria from the atmosphere and starts to ferments, a putrid odor will develop from the protein component of the urine and ammonic odor will develop from the ammonium salt. When ammonic odor becomes present, the pH of the contamination would have shifted to 10. Such high pH above the neutral average 3 to 5 of leather causes the amphoteric protein fiber to shift ionic negative (-ve); that causes the protein fibers to repels its other ionic negative (-ve) constituents like the tanning agent, fatliquor and dyestuff. Behaving just like the attraction of a magnet, like poles repel. When the leather constituent breaks hydrogen bond with the protein fiber, the leather starts to denature and revert to rawhide. A typical appearance of an aged or compounded contamination is a darkening effect from the fugitive tanning agents, a whitening effect from the fatliquor. Fugitive dyestuff or bleeding is only apparent from a white towel detection and yellowing from the urochrome. The denaturing or reverting to rawhide effect of the leather is further confirmed by tackiness or in worst-case sliminess in the present of moisture. The leach out fatliquor results in stiffness and fugitive dyestuff results in discoloration. A systematic sequence of decontamination approach includes surface residue removal with CleanUrine-1.5 (pH 1.5) and rinse with Acidifier-2.0 (pH 2.0) recharging the protein fiber ionic positive (+ve). Then neutralizing the ammonium salt with KillUrine-2.1 (pH 2.1). Utilizing such a low pH treatment retards bacteria activities from off gassing putrid odors, a natural pH control without the need to use bactericide or fungicide for mold prevention. Therefore, urine is a type of soiling that will require a biochemistry approach to decontaminate it. Restoring the leather begins after decontamination with Hydrator-3.3, a pH 3.3 multifunctional product that has ionic positive (+ve) charging abilities, an active surfactantcy essential for foreign water movement within the inter-fibrillary spaces to redistribute the leather constituents and purging foreign contamination to resurface. This is the last of the wet cleaning process to remove suspended urochrome yellowish compound through visible white tissue paper as an extension of the leather in the wicking process as the leather dries naturally. Only then, without a trace of the urine stain that Fatliquor-5.0 (pH 5.0) replenishing commences. The emulsified fat and oil encased water molecule breaks free when hydrogen bond attraction takes place between the fat and oil with the protein fiber, leaving a breathing space essential for leather transpiration to function naturally. The fat plumps the leather with fullness from easily collapsing into creases and wrinkles during stress or flex, while the oil lubricates the fibers so that they slide over one another like millions of inter-connecting hinges with smoothness. One important unique characteristic of leather is suppleness with strength and much depends on the fatliquor, in this holistic approach to effective leather urine decontamination and restoration. For severe neglected cases with finishes damages, refinishing commences after leather suppleness restoration.
