Before
deciding upon treatment, you should first access what ‘type’ of stain it is,
before a stain can be removed the surface tension that bonds it must be
released, then the stain encapsulated and held in suspension to be removed.
Use
a suitable (dependent upon the type of stain) 20% stain remover with in a
solution of and 80 percent distilled water, to remove stains from cloth seats.
Spray a small amount of the solution onto the stain. Wait for a few minutes,
and then scrub the stained area with a soft bristle brush or old toothbrush.
Blot the area with a soft clean cloth
Diagnosis
is the key, not guess work. With all cleaning products, always test a small,
inconspicuous area first to ensure it won't discolour or stain the surface, and
ensure that the pH of the product is suitable for the material. As can be seen
stain removal requires some knowledge of basic chemistry.
Depending
on the pH of the product you use you should return the surface to neutral (pH
7.0) before you apply any dressing or protective products. Always select a
chemical / cleaner that are biodegradable, environmentally friendly and safe to
use by observing any precautions recommended so that they won’t harm you, your
vehicle or the
Read
the product labels and manufacturers safety data sheets (MSDS) to obtain a
basic idea of contents, pH levels etc.
Classifying
stains:
a) Organic stains- these include proteins and fats, body
oils, mould yeast, bacteria, bugs and carbohydrates. Organic soil is cleaned
with an alkaline (pH 8+).Most of the stains found in the vehicle interior are
of an organic nature and require an alkaline type cleaner. Some organic stains
(i.e. milk, blood, vomit, urine) should be removed with an enzyme type cleaner
and a disinfectant applied to the area
b) Non-Organic stains- mostly found on the exterior of the
vehicle, hard water scale (calcium) lime deposits, Road tar, grease and oil
film, and require an acid (pH 6 or less) type cleaner.
c) Petroleum soils - substances that do not contain water,
nor are they miscible, these soil types include, motor oils, and crease and
road tar, and require a petroleum-based solvent type cleaner.
Stain
Types:
a) Water Soluble Stains- These stains can be dissolved in
cool water or loosened with water based cleaner, coffee; soft drinks, cocoa and
chocolate are good examples.
b) Oil soluble stains- These are stains that are comprised
of oily or greasy substances, which include cooking, oil from fried foods and
suntan oil.
c) Combination Stains- These stains contain both water based
and oil-soluble properties. Cleaning these stains require treatment with a
petroleum solvent followed by water based cleaning solution.
d) Unidentifiable Stains- Sometimes stains cannot be
identified. Treat these stains like a combination stain. Clean with a petroleum
solvent followed by water based cleaner.
As
can be seen with the above lists an all-purpose cleaner will probably not clean
stains effectively (Most are butyl based, which is a huge known carcinogen)
With all cleaning products (especially solvents) always test a small
inconspicuous area first to ensure it won't discolour, stain or etch the surface,
and ensure that the pH of the product is suitable for the material.
Stain
removal requires some knowledge of basic chemistry. Read the product labels and

won’t harm you, your vehicle or the environment. (See also Vehicle Interior
Detailing and Solvents)
All
Purpose Cleaner (APC)
As
you can see from the above list the so-called ‘all-purpose cleaner’ (APC)
cannot remove all stains, usually a high pH (6.0+) it’s better to use a
specific stain remover than to compromise. Always select a chemical / cleaner
that are biodegradable, environmentally friendly and safe to use by observing
any precautions recommended so that they won’t harm you, your vehicle or the
environment
Many
well-intentioned detailers use the so-called all-purpose cleaning (APC)
chemical for detailing. Using a product like Simple Green or a degreaser to
clean everything from wheels to carpets is both dangerous and harmful to the
materials used for modern automobile materials.
A
safer alternate is a Limonene (citrus-based) solvent, they are biodegradable,
environmentally friendly and safe to use. There is no such thing as a one size
fits all type chemical cleaner, regardless of what a car care product vendor
would have you believe.
Most
detailing chemicals are formulated to remove specific stains and a little
knowledge of their pH and chemical content will help in their correct selection
and use; the most common types of chemicals include surfactants, solvents,
wetting agents, Saponifiers and Chelators
Before
using a cleaning product a detailer needs to know the material they are working
on, what they are trying to remove and wither the product chosen is compatible
with the material and will not damage it.

Choose
carefully whose advice you listen to, and more importantly what advice you act
upon. The misinformation and myths that are so prevalent in the detail industry
is the reason that detailers need to do research on their own.
I
would strongly suggest that you verify any information that I or anyone else
shares with you. Treat all marketing
claims as being just biased marketing claims and if you're lucky they will be
based on truth and the company will operate ethically.
