Very Dark:
The very dark color is where the leather absorbs the body oil and grease. Besides the oil and grease, it soaks up our perspiration too; which may contains traces of protein and urea. Grease and oil darkens leather, compounded with perspiration that when fermented by the natural bacteria from the atmosphere, shift alkaline that also contribute the darkening effects too. It’s the bacteria activities that work on the traces of uric acid that gives off the smell if any.
Cleaning:
Oil and grease are degreased using Degreaser-2.2. This is a 2-in-1 process besides removing the penetrated grease, the low pH of 2.2 is also design to neutralize the pH shifting alkaline back to acid. One characteristic of alkaline, browns; and the reverse characteristic of acid lighten the color. This low pH of 2.2 helps to bring the pH of the protein fibers backs to its original chemistry integrity.
Lighten the Color Up:
Besides lightening up the color through degreasing and reducing the sun tanning effect just like our skin with d’Tanning-3.5; the hidden away from body contact and sun tanning pale biscuit color need to be season up as well with fatliquor.
The recommended sequence of processes is as follows:
1] Degreasing penetrated oil, grease and sweat with Degreaser-2.2 > Rinse-3.0
2] Optional ammonic odor is to neutralized with d’Urine-2.1
3] Optional decay odor is to be sterilized with d’Bacteria-3.7
4] Reducing sun tanning effect with d’Tannin-3.5
5] Leather rejuvenating with Hydrator-3.3 > Fatliquor-5.0
6] Non-stick, rub-resistant, draggy-feel, leather-scented protection with Protection-D+
Kit V3.tn is the recommended kit with optional d’Urine-2.1 and d’Bacteria-3.7 as add-ons.
