SPOTTING CHART I. 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. SPOTTING KIT CHECK LIST A. Regular 1. VDS- Volatile Dry Spotter 2. NVDS - Non-Volatile Dry Spotter 3.

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. I. TYPE OF STAINS A. Water Soluble Stains 1. 2.
