Degreaser - Body Oil, Grease & Sweat

Without a leather-safe routine or periodic care system like Leather Doctor Kit-A3 in place almost all absorbent aniline leathers will come a time when body oil, grease and sweat accumulates and penetrates into the leather structure especially the headrest and the armrest areas. Like an iceberg there is more beneath the surface than meet the eyes and the oil and grease is easier to emulsified and rinse off from the suede more porous side if possible. Besides effective degreasing, Degreaser-2.2 at pH value 2.2 is calibrated at a pH value lower then the pH neutral or isoelectric-point or pI averaging 3-5 of the leather to pH balance from the sweat contamination and protonating the amphoteric leather protein fibers ionic more positive (+ve) for stronger ionic attraction or hydrogen bonding with the other non-amphoteric leather constituents like the tanning agents, dyestuff and fatliquor. Weakening of the tanning agents ionic attraction leads to leather denaturing and is detected with a tacky or slimy feel and should be rectified back to a healthy squeaky feel. Bleeding control is rectified with strengthening of the ionic attraction and Acidifier-2.0 when work as rinse stabilized it. Emptied leather fibers of original fatliquor after degreasing should be fatliquor replenished while still in the wet stage to prevent leather stiffness that leads to cracking when dry in this holistic degreasing system with Leather Doctor Kit-A5.dr. The science behind the cleaning may sounds complicated but is well taken care off within this holistic system. The application part is a straightforward sequence of process with negative side effect reduced to the minimum depending on severity of the situation. In most situation when penetrated greased becomes apparent the topcoat is already damaged and will require a refinished, thus Leather Doctor Kit-A6.tc is the preferred choice.
