Carpet Stains, Stain Types, Stain Removal Methods

Carpet Stains come in two basic types. One, Spots are spillages that add substance to the carpet fibre. Two, Stains are spillages that adds colour or causes discoloration or loss of colour from the carpet.

Spots can easier to remove with some basic knowledge and off the shelf bought stain removers. Carpet stains on the other hand need skill and practice and come with risk in the correction and is more restoration than removal.

Removal Method 1

Carpet Stain Type

Includes: Light Oils, Grease, Petroleum, Substances Containing Fine Particles

Light Oils, Grease, Tar, Asphalt, Carbon, Toner, Graphite, Pens, Some makeup, Lipstick, Shoe Polish, Latex Glue, Candle Wax, Chewing Gum,

Stain Removal Method

  1. Volatile Dry Solvents, Tamp, Blot, Observe Transfer.
  2. Repeat until no transfer is observed. (consider using Non-Volatile Dry Solvents POG Paint, Oil, Grease Remover. Rinse out with Volatile Dry Solvents)
  3. Neutral Detergent Solution, Tamp, Blot, Observe Transfer.
  4. Alkaline Detergent Solution, Tamp, Blot, Observe Transfer (test colour fast).
  5. Rinse.

Oxidized Oils (old dried), Dry Pain Spots (latex, oil based, enamel), Floor Waxes, Crayon, Lipstick, Shoe Polish, Latex Glue, Some pigment dye, indelible Ink.

Stain Removal Method

  3. Repeat with patience until no more transfer. Use no more Non-Volatile Dry Solvents POG Paint, Oil, Grease Remover than needed to treat face yarns. (avoid saturating backing, secondary back carpets use latex glue)
  4. Rinse with Volatile Dry Solvents to remove Non-Volatile Dry Solvents POG Paint, Oil, Grease Remover residue. (avoids almost certain resoling).
  5. If colour remains, Alkaline Detergent Solution (test colour first) Tamp, Blot, Observe Transfer.

  7. Explain customers options and obtain disclaimer and permission.
  8. Residual colour (pigment dye) can be removed with Red Stain Remover and heat transfer procedures. Observe Change (Reaction).
  9. Acid Solution to accelerate reducer.
  10. Rinse thoroughly when colour is removed from stain.

Method Notes

Rapid expansion of indelible ink spots may be anticipated when treated with dry or wet solvents. Therefore, it may be necessary to apply vacuum suction to the backing (underside) of carpet during stain removal.

Removal Method 3

Carpet Stain Type

Since most “Non-Volatile Dry Solvents POG Paint, Oil, Grease Removers” contain Amyl acetate Stains in methods one and two could be combined and handled with one application of the same spotter. However, since a few companies still separate the spotters for petroleum oils (method 2) from spotter for synthetic resins (method 3) we discuss them here.

Includes: Synthetic resins, especially those that respond poorly to method 2.

Airplane glue, plastic, acrylic paint, nail polish, household cements, lacquer, varnish.

Stain Removal Method

  1. Volatile Dry Solvents (for penetration)
  2. Non-Volatile Dry Solvents (w/amyl acetate) Tamp, Blot, Observe Transfer.
  3. Volatile Dry Solvents, Rinse Non-Volatile Dry Solvents POG Paint, Oil, Grease Remover. Tamp, Blot,
  4. Acetone as last resort (not on acetate, test fibre) Tamp, Blot, Observe Transfer.
  5. Cautiously repeat until on more transfer.
  6. Volatile Dry Solvents to rinse Non-Volatile Dry Solvents POG Paint, Oil, Grease Remover
  7. Alkaline Detergent Solution Tamp, Blot, Observe Transfer.
  8. Rinse*

*Bleaching probably will not be beneficial, since colouring agents contained in these spots are usually insoluble pigments and are best removed with lubrication and suspension. Use of reducing agent like those in red stain removers may remove residual pigment,

Removal Method 4

Carpet Stain Type

Includes: Spots containing tannin (a weak vegetable dye), or old caramelized sugar.

Tannin, coffee, tea, cola, soft drinks, beer, fruit drinks, mixed drinks.

Stain Removal Method

  1. Blot excess and apply Neutral Detergent Solution (Penetrant) Tamp, Blot, Observe Transfer.
  2. Rinse face fabric and backings. flushing thoroughly.
  3. Acid Solution Tamp, Blot, Observe Transfer.
  4. Rinse thoroughly.
  5. If yellowish cast remains, rust remover (caution)
  6. Neutralise and rinse thoroughly.
  7. Explain customers options and obtain disclaimer and permission.
  8. Bleach, oxidizing (hydrogen peroxide 3%) Observe Change (Reaction) repeat until fibre colour lightens.

Method Notes

Tannin can be difficult to remove from protein (wool, silk) and some types of nylon fibres (In method 6) especially when the spillage spilled in still hot.

Determine whether the coffee in regular of decaffeinated as decaf contains dyes, again the hotter the spill the worse the stain.

Removal Method 5

Carpet Stain Type

includes: Foods, persistent protein spots.

Persistent protein substances, foodstuffs like gravy, starch, blood, faces, egg, milk, ice cream, urine, vomint.

Stain Removal Method

  1. Physically lift excess with spatula and remove.
  2. Neutral Detergent Solution (penetrate) Tamp, Blot, Observe Transfer. To avoid damage to acid dye blockers, its particularly important to stick with neutral spotters if carpet has stain protection applied.
  3. Patiently and repeatedly rinse excess with cool, neutral solution.
  4. Alkaline Detergent Solution, test colourfastness, Tamp, Blot, Observe Transfer.
  5. Rinse thoroughly to neutralise.
  6. Acid Solution, Tamp, Blot, Observe Transfer.
  7. Rinse thoroughly to neutralise.
  8. If discolouration remain, *digest.
  9. Rinse with cool solution.
  10. Repeat 6 and 7 as necessary.
  11. Bleach, (hydrogen peroxide 3%) Observe Change (Reaction) Rinse thoroughly.
  12. Reduce with sodium hydrosulphite, apply, wait 20 seconds, rinse, Observe Change (Reaction) repeat as required.

Digesting a stain

  • Sprinkle digester directly onto damp neutral (rinsed) protein stain.
  • place towel saturated with hot water on top.
  • Place bucket of hot water on top towel, to maintain warmth
  • Leave 20 to 60 minutes or longer for digestion to occur.

Method Notes

Most protein stains respond well with patience and cool, neutral detergent solution. Digestion is normally reserved for persistent or old stains.

Heavy urine spotting may require special formulations designed to loosen and suspend the yellow pigments, cholesterol, enzymes, bacteria, protein, etc.

Vomit contains hydrochloric acid, which may set dyes contained in many food stuffs.

The last traces of blood (tan yellowish discolouring) may respond to an application of 3% hydrogen peroxide.

Removal Method 6

  9. Acid Solution, to accelerate reducing agent, Observe Change (Reaction)
  10. Rinse thoroughly when stain colour is gone, but before colour is removed from the carpet.
  11. Bleach, (hydrogen peroxide 3%)
  12. Carpet sectioning ( cut and plug)

Low chance of removal with silk, wool, and nylon.
