2007 911 Porsche – what products you recommend for a matte finish and the distinct scent?

>>> I love the matte finish that the seats come with from factory, and would not like this appearance to change.

Any oily or greasy soiling or aged surface conditioner will build up a shine or alter its appearance.
The best approach is to strip all existing soiling or aged conditioner with Prep-7.7 > Clean-3.8 > Rinse-3.0 system back to the OEM topcoat. Protector-D will give a duller appearance then Protector-B+ and con be tested out on inconspicuous place to decide.

>>> Also, the smell, as you are undoubtedly aware, is distinctly Porsche. I would like a product that keeps this smell.

Protector-B+ or D+ comes with the classical leather scent, scentless is without the (+ sign).

>>> I am mainly interested in basic maintenance for the leather, not stain removal.
So I guess this means I am looking for a cleaning, and protector?

Basic cleaning maintenance periodically is by Clean-3.8 > Rinse-3.0
Restorative or corrective cleaning on a yearly cycle is by Prep-7.7 > Clean-3.8 > Rinse-3.0
Below surface leather rejuvenating is by Hydrator-3.3 > Fatliquor-5.0
Above surface finishes protection is by Protector-B+/B/D+ D.

>>> I wanted to know what your best advice is to stop creases, if there is any way?

Creases are reduced from compression and friction rubs by lubricating the surface with Protector-B+. The natural buttery-feel surface will cut noises when one slide in and out of the seat thus reduces formation of creases to a degree.

>>> I once heard that the creases are trapped dirt?

When dirt are trapped it becomes more obvious, when removed less obvious.

>>> Can old creases be removed from repeated treatment?

If the section of the booster can be hydrated through the finishes micro crazing, it will relax the creases and when fatliquor is replenishes will help to plumps the leather from overstretching does reduces the creases.

>>> Also, what is your normal advice for treating the leather i.e. products and regime?

You may want to form your own maintenance program by taking a year for corrective or restorative cleaning and 11 months for periodic maintenance as an example.
Thus starting with corrective cleaning in this sequence of process: Prep-7.7 > Clean-3.8 > Rinse-3.0 + Hydrator-3.3 > Fatliquor-5.0 + Protector-B+/B/D+/D.
Monthly periodic cleaning in this sequence of process: Clean-3.8 > Rinse-3.0 + Protector-B+/B/D+/D.
Perforated Panel: Monthly periodic cleaning in this sequence of process: Clean-3.8 > Rinse-3.0 + Hydrator-3.3 > Fatliquor-5.0 + Protector-B+/B/D+/D.

Leather Doctor Kit Ap3 – Auto Pigmented (perforated) Leather Care Kit
Leather Doctor® Kit Ap3, auto pigmented (perforated) leather care kit is an innovative leather-safe (pH 3 - 5) system designed for keeping leather interior at their highest level of appearance while maintaining their structural chemistry integrity and enhancing their suppleness with needle holes tear strength. Auto leathers are often under hot sun and those exposed to thermal heating during cold season dries out their fat and oil sooner. The first place to check for leather dryness is the stitching holes, if they are perfectly round the leather is healthy, dried out leathers will show signs of elongation or splits. The diminishing of the fat and oil will results in stiffness to the leather and when flexed or stretched during used will lead to cracks or rips first to the stitching holes. Periodic use of Hydrator-3.3 to hydrate the stick together fibers in these weak points prior to fat and oil replenishing with Fatliquor-5.0 will keep the leather supple with increase tensile strength. Thus, reduce the premature ageing of the leather against stiffness, tearing and cracking. Protector-B+ imparts a non-stick rub resistant protection with a buttery feel that makes sliding in and out of seat smoothly. The rub-resistant abilities reduce friction noises that translate into less friction wear especially to the side bolster. Periodic cleaning and rinsing with Cleaner-3.8 and Rinse-3.0 respectively to the steering wheel leather helps reduce greasy sticky soiling build-up. Removing of unwanted stains such as the common new blue jeans is accomplished with Prep-7.7. Note that the mentioned product suffix number denotes its pH value in this leather-safe holistic care system. This kit comes with reduced weight option to save on shipping thus the 250ml concentrate ratio such as Clean-3.8, Rinse-3.0, Hydrator-3.3 and Fatliquor-5.0 has to be cut or filled up with distilled water prior to use.
Instruction:

Preventive Care:
A non-stick, rub-resistant protection is recommended to be in place before putting the leather to daily use. Protector-B+ imparts a soft natural buttery-feel that enhances the leather luxuriously to the sense of touch. The non-stick surface shields the leather from sticky soiling thus prolonging the high level of appearance. Rub-resistant abilities reduces friction noises that translate into less friction wear as one slide in and out of auto seats effortlessly with less stress to the seat bolsters. This leather-scented protector diffuses a classic leather scent that boost the sensuous leather more appealing to the leather lover. This protection care commence at the end of each level of routine, periodic or restorative cleaning cycle. A simply spray and wipe prolongs the need for cleaning heavy soiling.
1. Apply Protector-B+ to the seats and Protector-D to steering wheel including the gear shift knob after shaking well spread with lint free towel and is ready for use when dry.

Routine Care:
Routine care includes procedures such as general dust cleaning, attending to spots and stains as required especially the neutralizing of swear stains from shifting alkaline. Thus prevents leather from tackiness. A routine non-stick rub resistant protection after neutralizing rinse helps keep leather interior in a more attractive and healthy state while preventing premature wear.
1. Spray Rinse-3.0, horsehair Brush-1 agitates and towel extract until it shows clean.
2. Apply Protector-B+ to the seats and Protector-D to steering wheel including the gear shift knob after shaking well spread with lint free towel and is ready for use when dry.

Periodic Care:
Periodic care is recommend before soiling causes damages to the finishing. This keeps leather consistently clean and healthy at all times. Driver’s seat would require more frequent attention than the other less frequent used seats. While the leather steering wheel and the gear shift knob get the most of body oil and sweat contacts.

1st phase – Periodic Care:
1. Spray Cleaner-3.8 and agitate with horsehair Brush-1; ensuring a uniform application over the entire surfaces a section at a time.
2. Towel extract until it shows clean.
3. Remaining residues are spray rinse with Rinse-3.0 and towel extract to a squeaky-clean.
4. Let dry and inspect for satisfaction, otherwise repeat cleaning process as necessary or proceed to hydrating.

2nd phase – Hydrating:
Although pigmented leathers surfaces are usually non-absorbent until micro crazing develops, it is the stitching rows and perforated holes that are usually vulnerable. These weak areas when wet and dry again have the tendency for the fibrils to become stick together resulting in stiffness and when stressed may lead to premature cracks. Hydrating is essential to relax and separate the stick together collapsing fibrous structure. Besides, charging the protein fiber ionic positive for a more effective hydrogen bonding with the ionic negative fatliquor.
1. Spray Hydrator-3.3 control and spread with foam brush to hydrate especially the stitching rows and perforated sections.
2. Let dwell 10 to 30 minutes depending on severity of dryness with optional plastic cling wrapping to control evaporation for a longer dwell time to plumps the leather more effectively.

3rd phase – Fat and Oil Replenishing:
Fatliquor evaporates as VOC (volatile organic compound) when temperatures rises especially from exposed micro-crazing, perforation and stitching rows. Periodic fat and oil replenishing maintains the leather’s structure integrity and pliability thus strengthen these exposed leather from cracking.
1. Spray Fatliquor-5.0 in like manner as Hydrator-3.3 and let dry naturally.
2. Repeat application in between drying until saturated.
3. Leave the leather for slow natural drying for extra softness.
4. Wipe surface strays with Hydrator-3.3 to free of sticky residue.

4th phase – Preventive Care:
1. Apply Protector-B+ to the seats and Protector-D to steering wheel including the gear shift knob after shaking well spread with lint free towel and is ready for use when dry.

Restorative Care:
Restorative care is the ultimate corrective or salvage care system that removes accumulated soiling including aged conditioners to its original OEM finishes. Accumulated soiling that fills creases is often mistaken for cracks. Restorative cleaning is performed by using Prep-7.7. It works by chemical reaction to emulsify soiling through its penetrating, lubricating and suspending power. Its thick as honey viscosity facilitates coating the surface for effective dwell time. Horsehair detailing Brush-1 is recommended to worked into heavily soiled areas sufficiently to avoid excessive agitation that might damage already weaken finishes especially on heavily used areas. For extreme cases, the Prep-7.7 can stay continuous for up to 72 hours to do its work safely.

1st phase - Restorative Cleaning:
1. Apply Prep-7.7 and agitate with horsehair Brush-1, ensuring a uniform application over the entire surfaces a section at a time.
2. Allow a dwell time of 10 to 30 minutes or before it dries prior to towel extraction until it shows clean.
3. Sticky residue is removed by Cleaner-3.8 with gentle brush agitation and towel extraction until it shows clean.
4. Remaining residues are spray rinse with Rinse-3.0 and towel extract to a squeaky-clean.
5. Let dry and inspect for satisfaction, otherwise repeat Prep-7.7 application with a longer dwell time as necessary or proceed to hydrating.

2nd phase – Hydrating:
Although pigmented leathers surfaces are usually non-absorbent until micro crazing develops it is the stitching rows and perforated holes that are usually vulnerable. These weak areas when wet and dry again have the tendency for the fibrils to become stick together resulting in stiffness and when stressed may lead to premature cracks. Hydrating is essential to relax and separate the stick together collapsing fibrous structure besides charging it ionic positive for a more effective hydrogen bonding with the negative ionic fatliquor.
1. Spray Hydrator-3.3 control and spread with foam brush to hydrate especially the stitching rows and perforated sections.
2. Let dwell 10 to 30 minutes depending on severity of dryness with optional plastic cling wrapping to control evaporation for a longer dwell time to plumps the leather more effectively.

3rd phase – Fat and Oil Replenishing:
Fatliquor evaporates as VOC (volatile organic compound) when temperatures rises especially from exposed micro-crazing, perforation and stitching rows. Periodic fat and oil replenishing maintains the leather’s structure integrity and pliability thus strengthen these exposed leather from cracking.
1. Spray Fatliquor-5.0 control and spread with foam brush to hydrate especially the stitching rows and perforated sections.
2. Repeat application in between drying until saturated.
3. The leather is left for slow natural drying for extra softness.
4. Surface strays are wipe with Hydrator-3.3 to free of sticky residue.

4th phase – Preventive Care:
1. Apply Protector-B+ to the seats and Protector-D to steering wheel including the gear shift knob after shaking well spread with lint free towel and is ready for use when dry.
