What is leather?
Leather is the fibrous corium or structural part of animal skins
as shown here in microscopic cross-section.

Leather comprises:
- tanned collagen (the protein which makes up skin and
bones),
- moisture,
- oils and fat.

Why your leather upholstery needs special care
Your automotive and domestic leather upholsteries are luxury items
that will keep their good looks and unmatched comfort for a very long
time if given proper care. However, in the real world they are under
attack from:
- Dirt and dust, which discolour
and abrade the surface. If allowed to remain, they can:
- be driven down into the leather where they
will begin to break apart the fibres, leading to tears and rips.
- cause both chemical and mechanical damage.
The sharp edges of minute dirt particles are abrasive, and can
damage the leather fibres.
- attract fungal spores, and acts as a centre
for condensation and subsequent chemical attack.
- Sunlight affects leather by:
- providing ultraviolet and infrared radiation
energy to the chemical breakdown of the collagen that makes
up the leather;
- oxidizing the colour coat leading to drying
your leather of its natural oils, cracking and fading;
- interacting with atmospheric pollutants, producing
chemicals that damage your leather;
- fading and cracking the surface colourant
or dye, although this is far less of a problem with modern coatings.
- Wind and heat affect leather
by drying the oils and moisture so that:
- the fibres that were once plump and flexible
become thinner, more rigid, and squashed together
- instead of flexing and stretching with use,
the fibres tend to tear. This process also happens in "wear
creases" in the leather, and progresses from a surface crack
to an actual split in the leather.
- "Accidents" such as:
- scuffs,
- tears,
- cuts,
- scratches,
- burns, and
- stains that can each spoil the appearance and reduce the life of
your leather upholstery.
How much Leatherique dye and Prepping Agent do I need?
The re-colour the interior of an average 4 door car, Mercedes
Benz, BMW, Jaguar, Lexus, Toyota , or the average sofa will
require 1 Litre of dye and prep.
A smaller sports car, Ferrari, Corvette, Porsche, Jag XJS or
a recliner or chair and ottoman will require 500ml.
This is based on re-dying the same colour.
Larger cars with extravagant amounts of leather like a Rolls
Royce or Bentley will require a 1 ½ - 2 litres of dye and
Prepping Agent..
Extreme colour changes may require more dye for good coverage
of all the leather and trim parts.
Leather Care tips
Sun and heat rob your leather of its natural oils, leading to
cracking and fading. Dirt, dust, grit, and grime discolour the surface
and, if allowed to remain, will be driven down into the leather
where they will begin to abrade and rot the fibres, leading to tears
and rips. Therefore, it is vital to vacuum your leather upholstery
every few weeks, especially along the seams and pleats, followed
by a wipe over with a slightly damp (not wet) towel (without detergent).
Leather should be cared for as you would your own skin. We would
never seal our skins in plastic wrap! They would shrivel and dehydrate
from lack of moisture and oxygen. Why use Silicones based products,
which prevent the delicate leather fibers from receiving nourishment
on our leather?
We should clean our leather, as we do our skin, with gentle,
deep cleaning products, not harmful chemicals or drying spirits.
We should moisturize and lubricate our leathers with the best moisturizers
available to keep the fibers clean and strong.
