Leather seat Rain and Sunburn Damaged for 2 days!

Pictures have shown unequal shrinkage between the leather structure beneath the finishes coatings (colorcoats and topcoats), with the finishes rippling and may show peeling or delaminating once the beneath leather structure is hydrated back to the original dimension. Any white residue resurface my be that of fugitive fatliquor that has been displaced by the breaking of bonds between the leather protein fibers.

Leather has an average pH value of 3 to 5, any solution including the rainwater averages 7 or depends on location “acid rain” with a lower pH value but if it is still above the iso-electric point of the leather or (pI) will cause the protein fiber to shift its pH value to ionic negative (-ve). Fatliquor like Fatliquor-5.0 is ionic negative (-ve) as well. Thus like poles of magnet repels each other causing the leather to denature and revert back to rawhide.

>>> Is there any ways to modified it by using certain kind of chemical agent?
The surface soiling if any is clean with Clean-3.8 before neutralizing the rainwater and protonating the protein fiber with Acidifier-2.0 (pH 2.0) simultaneously.

>>> Do I need to keep it in the parking desk for several days?

Relaxing or hydrating is done with Hydrator-3.3 using a stretchable paper as a reservoir with plastic cling wrapper for evaporation control to slowly penetrate into the leather structure to plumps it up. This technique only lets the Hydrator-3.3 go one way that is into the leather structure rather than evaporates too soon into the atmosphere. Not heat is require for this process but much depends on constant replenishing until desired reverse shrinkage is achieve.

>>> How long will it take for the leather to dry out?

Once the leather is reverse shrunk to satisfaction the dimension is maintained with introducing fatliquor-5.0 into the leather while the moisture or water contents evaporates until the leather is fully saturated with fat and oils when dry.

>>> What can I do right now?

The above explains what can be done, meanwhile any pressure or stress to this parts may easily leads to cracks.

Note:
The crumple or distorted finishes may not automatically fall in place if they have become delaminated and may need refinishing.

Leather Doctor Kit At5.ws – Auto Leather Water Stain Removal Kit

Leather Doctor® Kit At5.ws, auto leather water-stain remover kit is design to remove water stains as the results of destabilizing the leather pH equilibrium. The side effect of alkaline overexposure manifests as marks and rings behaving like litmus paper. The darkening rings are leather constituents that breaks bond with the protein fiber and migrate forming the outer ring. Stains are clean with Clean-3.8 to remove surface residue prior to Acidifier-2.0. Acidifier-2.0 neutralizes the alkaline overexposure recharging the protein fiber ionic positive to re-attracts the ionic negative leather constituents. The leather is saturated and dwell up to 72 hours for extreme cases to facilitate redistribution and wicking up foreign contamination. A paper tissue covering without airspace helps trapped stains instead of remaining on the leather surface when dry. Hydrator-3.3 helps to redistributes the inter-fibrillary colloidal water movement; bringing the remaining stain to surface prior to fat and oil replenishing. Fatliquor-5.0 rejuvenates and imparts leather with softness and suppleness when dry. Protector-B+ enhances a non-stick rub-resistant protection with a buttery-feel that shield against sticky soiling. Note that the mentioned product suffix number denotes its pH value in this holistic leather-safe aniline leathers pH stabilizing system to eliminate water stains. Leather protein fiber is an amphoteric material while the other leather constituents like the tanning agents, dyestuffs and fatliquor are not. The iso-electric point (pI) of leather averages pH 4, water averages pH 7. Between pH 7 and pH 4 there is an ionic difference of 1000 (one thousand) times. Foreign pH influences below the pI charges the protein fiber ionic positive while above the pI causes the protein fiber to shift ionic negative. The ionic leather constituents and the protein fibers behave like magnets, unlike poles attracts. This kit comes with reduced weight option to save on shipping thus the 250ml concentrate ratio such as Clean-3.8, Acidifier-2.0, Hydrator-3.3 and Fatliquor-5.0 has to be cut or filled up with distilled water prior to use.
