DEFINITIONS
Definitions from the S001-1994 CLEANING STANDARD says this about spots and stains:
Page 37
spot - The result of a material adding substance or texture to a fabric or surface. Usually the
terms "spot" and "stain" are used interchangeably in a non-technical context.
spotting - The process of treating isolated spots and stains, that do not respond to normal
cleaning with, specifically formulated agents.
stain - the result in a material adding color (without texture) to a fabric or surface, in a nontechnical context. The term "stain" is often applied to discoloration, or color removal from
fabrics, as well.
Consumer responsibility for spots and stains in the S001-1994 CLEANING STANDARD says
this:
3. Immediate Spotting - Most spots can be removed easily if the excess is lifted or blotted and
treated immediately by carpet owners with plain water, or with spotters containing mild (pH range
of 5 to 9), dilute detergents that do not leave residue. If ignored those spots, or components
thereof, may bond with fiber dye sites, forming permanent stains. Immediate spotting is an
essential responsibility for home and business owners/managers.
Concerning what the consumer can expect from the cleaner is says this on page 8:
g. Special attention to spots and stains must be included in normal job performance. However,
time consuming specialized spotting of quantities of spilled materials or prolonged effort on coloradded spots may incur an additional charge. Customers should be advised of additional charges
before extensive spotting procedures are undertaken.
Rules for Spotting
.APPEARANCE - Spots that are lighter than the surrounding unaffected area
are the result of color loss. Spots that are darker than the surrounding
unaffected areas are the result of something added. Spots that end-up
changing in different light and diminish or disappear in direct intense light
are the result of texture variations, usually from over aggressive mechanical
action.
.HEALTH & SAFETY - Protect yourself with gloves, face mask, and respirator
when using dangerous chemicals. Dangerous chemicals such as
Erusticator, and strippers, and some solvents should be rinsed out
completely after using.
.CHEMICALS - Physically remove as must excess of the spot as possible
before adding chemicals. VDS is the first chemical to use on an unknown
spot. Strong oxidizers, strippers are the last chemicals to use.
.APPLICATION - Do not distort the texture of the fiber. Tap and blot, do not
brush and rub. Work from the outside of the spot to the inside. Blot up
excessive usage of chemicals. Wait to evaluate the results.
I.
Chemical Terms
ACETIC ACID- Acetic acid, HC2 H3 O 2 , pH 2.4, is a self neutralizing, evaporating acid of which white
vinegar is a 5 to 7% solution. White vinegar can be made into a tannin spotter by mixing it with two
parts water. Professional concentrations of acetic acid vary from 5 to 28%.
Acetic acid is most suitable for applications that require starting with an acid and then switching to
an alkaline or vise-versa. It is not a satisfactory remedy for pH problems on yellowing and indicator
dyes.
AMMONIA & AMMONIUM HYDROXIDE - Ammonia, (NH3 ) is a gas while ammonium hydroxide,
(NH4 OH), is an alkaline liquid. Ammonium hydroxide will self neutralize its pH after being applied to
a textile.
Ammonium hydroxide is not a suitable for correcting problems with acid residues such as in the
case of color changes from indicator dyes.
ENZYMES - The enzyme component of a spotter or prespray is an extract from a live microbe, but
is not a living thing. Two advantages that distinguishes enzymes from other detergent components
are:
 it decomposes components of soil with no effects on the textile
 it is not used up or consumed in the process.
This is in contrast to alkali, solvents, and surfactants that can cause ill effects on the textile and are
consumed in the process of removing soil.
Disadvantages of enzymes are they will slow down or stop working if the pH and temperature are
not right. With the arrival of Enzyme Presprays, the pH of many products is much higher than the
products of the 80’s.
HYDROGEN PEROXIDE - Hydrogen peroxide (H2O2), is a liquid that is
made from O-Zone (O3) reacting with water, (H2O). The result is a medium
strength acid oxygen bleach that is suitable for spotting textile in
concentrations under 5%. Hydrogen peroxide does its work when it breaks
down and can be accelerated by adding a trace of ammonium hydroxide.
Phosphoric acid will stabilize hydrogen peroxide and prevent it from
reacting and acetic acid will react making a new compound called peracetic acid. Per-acetic acid can bleach the color from nylon and should be
considered a strong oxidizer. Hydrogen peroxide left un-reacted can
increase in concentration in the drying process causing damage to textiles,
specially on natural fibers such as cotton.
pH - pH is the standard method for describing acidity or alkalinity. It is a
scale that starts with 0 and goes to 14, with 7 being neutral or pure water.
Below 7 is an acid and above 7 an alkaline. A change of one represents a
10 fold increase or decrease in the amount of acidity or alkalinity.
Expanded understanding of acids and alkalines reactions includes
information on molar strengths, (concentrations) and the reactivity, (G).
For example sulfamic acid has a very low pH of 0.47, but is not very
reactive.
SODIUM PER-CARBONATE - Sodium per-carbonate is a powder, alkaline, oxygen bleach that is made
from hydrogen peroxide and soda ash. It is suitable as a detergent booster or spotting agent. Sodium
per-carbonate can leave an alkaline residue in excess of pH 11.
VOLATILE DRY SPOTTER, (VDS) - Commonly this product is or was 1,1,1 trichloroethane, (CH3CCl3)
which is a slightly flammable, fast evaporating dry-solvent. Due to changes in the law, newer Volatile Dry
Spotters are blends of possibly more toxic and/or flammable solvents. Volatile Dry Spotter should be the
first spotter used on an unknown spot. It is not totally effective on paint without the help of non-volatile
solvents.
NON-VOLATILE DRY SPOTTER, (NVDS) - Commonly referred to as POG or PAINT, OIL, & GREASE
REMOVER, is a blend of solvents that is mixed into a crude refinement of petroleum. As such, some of
this blend will not. Evaporate completely. Non-Volatile Dry Spotter slows down the evaporation rate of
Volatile Dry Spotter and is an essential step in removing some forms of paint. Some newer products are
more ‘gel like’ and are made of blends of water and d-limonene.

PRE-INSPECTION & IDENTIFICATION
A.
The first step in identification is to ASK the consumer what the
stain is.
B.
The second step comes from SIGHT.
1.
A splash or irregular pattern likely came from something spilt.
2.
A pattern such as circular or rectangular probably came from
something laid on the surface.
3.
A shiny stain is likely from
a)
Hardened Oil
b)
Paint
c)
Varnish
d)
Nail Polish
4.
A dull appearance that lightens when scratched is likely from
food.
5.
A spot that is lighter than its surrounding was likely caused by
a bleaching agent or from color loss.
A. The third step comes from TOUCH. Categories for touch
are as follows: crusty, hard, soft, tacky, oily, wet, and waxy.
B. The fourth step comes from SMELL. This may be the
best instrument for identification, but it is subjective too.
Also, caution should be given concerning inhaling toxins
from chemicals and bacteria.
C. pH is important when a spot does not respond to
solvents. pH reading from an electronic instrument will
likely be less than those taken from paper or strips. This is
so because moisture on paper or strips will ultimately
measure the dry pH while pH Pens measure a diluted pH at
the time of the reading.
