    Default Aniline (Sauvage) - Aniline leather sofa urinated by puppy…on several occasions.

    I came across a post that mentioned your products.
    I have a leather sofa that was urinated on by a puppy...on several occasions.
    It has dried and I want to restore the seats to the best condition possible.
    Here are a couple of pictures of the couch.
    My wife tried to clean it up after it happened.
    She bought something at the pet store that neutralized enzymes...or something to that effect, but there is still significant staining and the leather feels stiff.
    Smell is not so much an issue.
    Can you give me more information about the products and cost?

    >>> I have a leather sofa. . .

    This leather finishes type is identified as “Aniline Savage” with a gloss topcoat with the entire natural skin/hide characteristic shown through.


    >>> urinated on by a puppy...on several occasions.


    Urine when aged will produce an ammonia odor or smell at a certain stage and the pH value would have reach 10.
    This shifting of its pH value from almost 7 to 10 denatures the leather and may be detected as tacky. Leather protein fiber is an amphoteric material and alkalinity above its average neutral pH 4.0 shift it ionic negative (-ve), thus repels its other leather constituents like the tanning agents and fatliquor besides displacing its dyestuff from the center of alkaline overexposure. Neutralizing the pH with low pH solution and eliminating the ammonia smell is the key to decontaminate the leather.

    Most of these enzymes solutions has a neutral to alkaline pH value and most likely have compounded the alkaline overexposure. The dark stain shown may not have been there prior to your failed attempt; these dark stains are most likely the fugitive tanning agents. The white cloudy residues are probably fugitive fatliquor resulting from the leather for being feeling stiff.

    Leather Doctor Kit A5.uk – Aniline Leather Urine Killer Kit Leather Doctor® Kit A5.uk, aniline leather urine killer kit is designed to decontaminate urine problems. 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 with wet finger testing it. This stickiness is a sign of leather denaturing and reverting to rawhide. pH balance to stabilize the denaturing leather is rectify with Acidifier-2.0 prior to cleaning the protein residue with d’Protein-10. Rinse-3.0 may follow prior to treatment with d’Urine-2.1. 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 prior to fat and oil replenishing with leather scented Fatliquor LS-5.5. Protector-B+ enhances a non-stick rub-resistant protection with a buttery-feel that shield against sticky soiling with a classic leather scent. In severe cases color refinishing is the last resort to restore appearance. Note that the mentioned products suffix numbers denotes its pH value in this holistic approach for perforated-leather urine decontamination process.

    Leather Doctor Kit A6.tc – Aniline Leather Topcoat Refinishing Kit
    Leather Doctor® Kit A6.tc, aniline leather topcoat refinishing kit is designed for topcoat repairs from friction wear, accidental scratch, scuff and abrasion to deteriorating greasy sweat stains. These topcoat damages are identified as white, dull or darkening stain from bare body contacts. Accidental whitish damages in most cases are free of soiling and direct AnilineTop-21G application with in between dry sanding rectifies most damages. Repairs to topcoat from daily wears that dulls will require a degreasing to remove penetrated rub-in soiling prior to topcoat application in a sequence process including Degreaser-2.2 follows with Rinse-3.0; Hydrator-3.3 follows with Fatliquor-5.0 prior to topcoat application. In a greasy and sweaty topcoat damaged areas especially to the headrest and armrest, a deep degreasing is essential follows with Acidifier-2.0 to stabilize the hydrogen bonding between the protein fibers with the other leather constituent like the tanning agent, dyestuff and fatliquor. This deep degreasing process is assisted by leather Eraser-4 in both the wet and dry cleaning process to remove soiling particulates off the leather surface. Hydrator-3.3 helps in the colloidal water movement bringing suspended soiling particulates to resurface through a dwelling and wicking process. Fat and oil is replenished by Fatliquor-5.0 in an emulsion form to penetrate into the leather structure. Once the fat and oil is hydrogen bond with the protein fiber, the water content breaks free leaving a breathing space for natural transpiration. The fat plumps the leather with fullness preventing the leather structure from collapsing during compressing and flexing while the oil lubricates the fiber from sliding smoothly over one another like millions of connecting hinges. Protector-B+ impart a non-stick, rub-resistant surface with a buttery feel helps reduce friction wear to the topcoat and extended a high level of appearance for a longer period of time. When the leather is contaminated with foreign soiling, it is essential to look at topcoat refinishing in a holistic approach. Note that the cleaning and rejuvenating products suffix denotes its pH value in this leather-safe aniline leathers topcoat refinishing system.
