How to Identify Leather Stains?
Leather Stains are identified by: Appearance, Odor, Color, Feel-of-Hand, Location, and Buildup or Absorbed!
1: Appearance:
1.1: Stain identification by appearance will show whether it is the characteristic of a spill, rub-on, penetrated, or deposited.
1.2: Stain may also reveal dye or finish damages caused by the stain.
2: Odor:
2.1: Odor-by-smell identification can be helpful in positive stain identification.
2.2: Odors such as moldy, smoke, putrid, or ammonia from urine are some common stains identified by smell.
3: Color:
3.1: Color stain identification will also give a clue to the staining stuff.
3.2: Color stains from beverages, nail polish, lipstick, blood, or others could all appear red.
3.3: Color identification may not be necessarily right; with time and oxidization, a red bloodstain may turn from tan to black.
3.4: The color of the leather may mesmerize or alter the appearance of the stain.
4: Feel of Hand:
4.1: Feel-of-hand stain identification may help determine the stain types.
4.2: A candy, beverage, or a sugar substance could appear red and feel sticky.
4.3: A nail polish, shellac or paint stain may feel brittle and stiff.
4.4: A grease base stain such as lipstick may smear by the feel of the hand.
5: Location:
5.1: Location may give a clue as to the makeup of the staining substance in visual inspection and identification.
5.2: Dark stains from body oil, grease, and sweat are common on the headrest and armrest of furniture.
6: Buildup or Absorbed:
6.1: A stain may take several appearances.
6.2: Most stains build up or accumulate on top of non-absorbent pigmented leather.
6.3: Almost all stains are absorbed on most unfinished, aniline, and nubuck leathers.
6.4: Naturally, stains could also combine absorbed and built up.
6.5: An absorbed stain indicates that it was a liquid before it penetrates the leather.
6.6: A liquid stain may have chemically changed and destabilized the leather
chemistry integrity and alter its appearance.
6.7: Example of sweat stains often react with absorbent leathers and denatures them.
6.8: Examples of stains affecting the tanning agent that preserves the leather manifest as tackiness when dry and sliminess when wet detected by the feel of the hand.
6.9: Examples of stains affecting the dyestuff occur when color appears during wet wiping with a white absorbent towel.
6.10: Examples of stains affecting the fat liquored leather fat and oil leaching out as a milky film known as leather spew, the leather becomes stiff, loses its tensile strength, and cracks when stressed.
6.11: In any event, the leather may show a marked color change in that area after spotting, and possibly after cleaning.
6.12: Examples of built-up stains include paint and some foodstuff, etc.
6.13: Examples of absorbed stains include beverages, wine, tea, coffee, etc.
6.14: Examples of combination stains include lipstick, ink, mustard, etc.
6.15: Most absorbed stains will have part of their staining stuff absorbed into the leather and part accumulated on its surface.
6.16: A stain may also be a substance that has wet solvent-soluble and dry solvent-soluble components combined.
6.17: Examples of a compound stain would be gravy which contains grease, flour (from a plant), and milk (from an animal).
6.18: Examples of paint-type stains are readily detected because of their stiff nature and generally bright colors and they seem to be sitting on top of the leather.
6.19: When identifying stains always try to determine whether they are of a protein, cellulose, oil-based, or a colloidal make-up in nature.
6.20: Three common types of soiling or stain are solvent-soluble, water-soluble, and insoluble.
6.21: Stains are often of a combination in nature, and in most instances, there will be no information regarding the stain especially if they are bought used.
