Fresh urine typically has little odor.
The offensive urine smell begins once it starts to decay with bacteria activities that feast on the organic compound stain and release ammonia gas.
The second stage releases mercaptan, a foul-smelling organic compound.
Urine begins as an acid but the remaining phosphor salts are alkaline.
This alkalinity may strip the acid dyes & colors causing discoloration to the leather.
On finished leather the salt resurfaces as white circular marks, especially noticeable on darker leathers.
Decontamination procedures are prescribed as follows:
Step 1
These alkali and ammonia salt should first be neutralized with urea2.1™
urea2.1™ is a pH 2.1 aqueous acidic spotting agent that contains a choice ingredient for urine stain on all leathers, including nubuck or suede. Developed to neutralize the ammonia and alkali phosphorus salt found in urine as the first phase.
Step 2
A bio-enzymatic digester bioEnz4.7™ helps break down the compound stain as the second phase.
Step 3
Then follows with protein11.0™ to remove the remaining residue as the third phase.
Step 4
Complete neutralize with acidifier2.0™ to balance to leather neutral pH of 3 – 5.
Step 5
Clean with cleaner3.8™ of all residues.
Step 6
Follows with acidifier rinse, rinse3.0™.
Step 7
Replenish original oil lost with fatliquor5.0™, a spray version of the tannery fatliquoring process.
Otherwise this area becomes stiff and will eventually crack.
Step 8
Treat with anti-microbial mold3.6™ to control microbial activities.
Step 9
Restore the unforgettable classic leather scent with leatherScent™ B (buttery), D (draggy), S (silky) or W (waxy).
When customers are not prepared to accept all these steps, I wouldn't touch it (It becomes a trap!).
The alkalinity and bacteria activities are working towards denaturing the leather, which will eventually rot the leather.
The smell is merely the smoke screen.
The alkalinity and bacteria activities are the main culprits.
Leather Safe is leather cleaning products that has a pH value of 3 - 5.
Developed to work in harmony with the healthy pH value of leather.
