German guys - what leather conditioner can I get in a store

That is good?

Right now I us Lexal but I ran out while doing my wife car. I am shipping my car back to the US in early May and I would like to let the leather soak in the conditioner while it sits on a boat for 6-8 weeks.

I need something that I can get in a store in Germany. Maybe something by sonax?

Not sure about what you can find in Germany; really, there is no rush (see below).

You don't want to let wet conditioner sit on seats for 2 months... #1 it will dry and then possibly dry the leather and #2 every single conditioner made for leather comes with instructions to wipe off excess product from immediate-24 hours (to my knowledge)

I mean, you can condition the leather before the car leaves, but don't leave the excess on...

kjang you are on the money. What I meant by sitting for 6-8 weeks is that the leather will be nice n clean with a coat of conditioner in it and that it wont be used for a long time. I am looking for something that can take the place of Lexal until I get to the US this summer.

I doesnt have to be great, just something that will be compatible.

Finished leather Cleaning / Care

Using the correct products is important in order to protect your car’s interior. If you keep your cars’ interior clean, you can easily save your car for a good couple of years and it can stay in a ‘like-new’ condition, and maintain a better re-sale value. Cleanliness is one of the major things buyers look for when purchasing a vehicle. There are several leather upholstery cleaners available, which need to be used in accordance to the type of finished leather upholstery that is fitted to your vehicle.

Automotive leather and finished leather surfaces have undergone major technological improvements over the past decade. Nearly all automotive leather surfaces are treated with special chemicals that provide resistance to abrasion, scratching and marring, increase their durability, and provide protection from weathering.

Unless a Premium Leather option was purchased the type of leather upholstery used by ~ 95% of OEM is a multi stratum covering over the leather hide; the top strata is the surface pigmentation (colour) and an abrasion resistant urethane. Real leather has a recognizable fragrance that is missing from polyurethane and plastic. Simple cleaning, hydration and protection are the steps that will prolong the life of finished leather.

Top-grain premium leather is mostly used in prestige European automobiles; Aston Martin, Bentley, Ferrari, Jaguar, Lotus, and Rolls Royce, US Cadillac and high-end German automobiles such as; Audi, BMW, Daimler AG, Mercedes-Benz, and Porsche, for most of these vehicles premium leather is standard OEM specified equipment, but for most it’s a ‘premium’ package that costs upwards of 2,000 USD . This is the niche market sector both Leatherique and Connolly were originally formulated for.

I’ve always been amazed that such a simple detailing task like the cleaning and care of finished leather upholstery has been made into something so complex, the only people who have anything to gain from this have a vested interest in the sale of products. The use of oils, replacement of fat liquor, oil-based conditioning or the adjustment of pH levels is totally unnecessary; the surface is a urethane that contains pigmentation (colour) it neither needs or benefits from any of the above

Modern automotive leather upholstery use a completely different tanning processes and finishing system, utilizing advanced polymers and chemicals (urethane doesn’t require conditioning or rejuvenation) and as a consequence they do not need to be treated with aftercare products containing oils or proteins

I looked at a detailing care product vendor site and found nine (9) pages of leather care products, mostly expensive oil-based leather ‘conditioners’ this could be the reason they ignore an appropriate care product for the upholstery material actually used for automotive upholstery. So it makes sense (or should that be dollars and cents) that they may be reluctant to make comments on leather conditioners

An acrylic and polyurethane resin binder system is used to improve flexibility, fastness and adhesion to the leather, then two or three aqueous (water- based) pigmented base coat applications, and then a clear aqueous (water- based) top coat is applied, which usually includes additives to give it a soft feel and abrasion resistance as well as a limited amount of ‘slide’ to assist in entering and exiting the vehicle as the final stage of the finishing process.

Identifying characteristics - this type of surface; it will also have an even shine.

The water-drop absorbency test- water drops will ‘bead’ on the surface

Absorbency rate -Low

(a) Clean - there are two cleaning-related factors that can cause your leather to wear prematurely. The first is dirt, and the second is oil, combined they become very abrasive, as dirt / grit and subsequent friction cause the finish to wear. Use an aqueous (water- based) foam cleaner (Leather Master™ Foam Cleaner) a foaming action makes it especially safe for Aniline, heated seats and perforated finished leather surfaces. Foam encapsulates the dirt so that it can then be wiped away; allow the foam to dwell to ensure the chemicals have time to work.

For stubborn dirt use Leather Master™ Strong Cleaner, which can be diluted with distilled water to the required strength; do not apply any liquid cleaning product directly to the surface of finished leather, as it may ‘spot’ clean leaving a faded area? Always apply cleaning products to folded 100% cotton micro fibre towel and then apply using light / medium pressure.

For ingrained soil the best results are obtained by cleaning the leather with a sponge or a medium soft bristled brush to agitate the cleaner, this ensures a thorough cleaning

(b) Hydrated – when leather tanner’s talk about conditioning leather they are referring to its moisture content, re-hydration is used to restore or maintain fluid balance (transpiration and evaporation of moisture); not the replenishment or replacement of the fat liquoring, oils and / or waxes.

Water molecules are smaller than the molecules found in polyurethane top coats, so it can permeate the finish in vapour form. This is essential to restore the suppleness and maintain leathers natural flexibility and keeps the leather at its optimum physical performance level, along with softness and strength.

Modern finished leather needs to be kept hydrated with moisture to ensure the leather remains flexible and maintains its soft tactile feel. This is done by regularly wiping the surface with a damp 100% cotton micro fibre towel and by using aqueous (water- based) leather care products. There is no reason to use oil-based leather care products to condition or feed leather hides

Finished leather require oils to feed / nourish it

This is based upon oil-based pigments, nitrocellulose lacquer or enamel and older technology pigmentation on classic vehicles required oils to keep them from becoming too brittle and cracking, water-based high solid/low solvent and urethane pigmentation only require hydration and protection

Leather is hygroscopic and so moisture is the most important element (median15 %) in the care of leather; all changes in leather are due to moisture differences. Too little moisture (< 10%) will cause the leather to become hard and inflexible, too much (> 20 %) and it may the fibres to swell and may cause mould formation.

A regular wipe down with a damp towel on a regular basis is all you need to condition and / or hydrate finished leather, and by using aqueous (water- based) products that do not contain oils and/or waxes, check the label if they do then don't use them. Leather should be hydrated on a regular basis and is somewhat climate dependent. Monthly hydration of leather upholstery in most southern states; Florida, Texas and Arizona, and etc especially during the summer months, would not be out of line

(c) Protected - is essential as it will protect the surface finish (Leather Master™ - Protection Cream) as a sacrificial layer; this way you are not actually cleaning the Leather's original surface, but cleaning from the surface of the protection. It also makes dirt easier to clean off

Leather Master™ - Protection Cream (a Scotchgard™ type product specifically formulated for lather) the polymers penetrate the surface of finished leather and cross-link to form a durable protective film that is breathable and keeps the leather supple.

Being aqueous (water- based) it restores moisture to finished leather and provides a protective sacrificial barrier against all kinds of soiling, water, oil, alcohol-based stains and perspiration marks, so you are cleaning the protective layer

Ultra violet (UV) protection - 303® Aerospace Protectant will provide invaluable UV-B against photo degradation (fading) protection; especially in a roadster or convertible vehicle

(d) Patina(softness) - used to improve and maintain the tactile feel and lustre to ensure the finished leather remains soft and supple; apply Leather Master™ Soft Touch (ex Soft Vital) and allow to dry for approx 20 minutes, finally using a clean dry 100% cotton micro fibre towel buff to a matte sheen.

This product is NOT a conditioner per se but is used to restore the softness to hard finished leather; place the car in a sunny location and roll down the windows. Allow the car to sit in the sun for one or two hours to warm the surfaces.

Umm yea. I just need a brand name or product name. I know how to use that stuff but I ran out of the stuff I use and I dont have enough time to get more before I have to ship my car.

I didnt blow $50k on my car to baby it. I use it and abuse it and then I clean the hell out it so it looks pimp again before I use it and abuse it again.
