Invisible Stains: Information & Resources

Last Updated on September 26, 2024 by Alterations Express Staff

We know… You think we’re making it up. Invisible stains?!? I mean, it certainly sounds like something we could’ve made up. But, we promise, they’re real. And they show up at the most inconvenient times and also the most inconvenient places, too. Check out our article below for all the information you need about invisible stains, their causes, prevention, and who is responsible for them, too.

What are Invisible Stains?

Invisible stains are mysterious stains that sometimes appear on clothes after a period of time in storage. These faint or  ‘invisible’ stains to the naked eye typically only appear after a garment is cleaned and exposed to steam or heat.

The Different Types of Invisible Stains

1. Color Loss

Color loss invisible stains occur when products containing alcohol or bleach stain a garment and appear ‘invisible’ to the naked eye at first. Then, oxidation occurs over time to reveal the stain. However, the chemicals within bleach or alcohol stain result in color loss when the garment is exposed to heat during the dry cleaning, steaming, or pressing process. The heat from the cleaning process accelerates the chemicals and, thus, results in color loss of the fabric.

Products That Can Cause Color Loss Stains:

• • Alcoholic Beverages
  • Perfume/Cologne
  • Skin Refresher
  • After Shave
  • Hair Spray & Hair Care Products
  • Lotions
  • Some Medications
  • Home Bleaches, Disinfectants, Cleaning Agents

2. Fiber Damage

Fiber damage happens when holes appear after cleaning when no damage was noted before the cleaning process. This type of invisible stain problem is known as fiber damage. Fiber damage during the cleaning process occurs when a garment has been attacked by insects while in home storage. The insects feed on the fabric and weaken the fibers. Then, during the dry cleaning process, the garment is exposed to agitation and heat, and those weak, cut fibers fall out to reveal holes where there previously was not any damage. Although rare, fiber damage can also occur when the fabric is exposed to harsh chemicals.

Insects & Chemicals that Cause Fiber Damage:

• • Moth Larvae
  • Cockroaches
  • Silverfish
  • Carpet Beetles
  • Acids or Chlorides
  • Perspiration & Anti-Perspirants
  • Acid Beverages, Mineral & Battery Acids

3. Oxidized Oil Stains

An oxidized oil stain is a yellow, tan, or rust-colored stain that appears after the dry cleaning process. Oxidized oil stains are caused by vegetable or cooking oils, mayonnaise, or other oils found in foods, lubricating or medicinal oils, linseed oils, or oils in lotions or salves.

These stains are often initially invisible; however, over time, they become oxidized (absorb oxygen from the air) from regular atmospheric exposure and thus discolored. Heat exposure during the cleaning process accelerates the oxidation and speeds up the formation of the stain.

Acting as quickly as possible will give you the best chance of removing oil stains. However, in most cases, total removal is impossible.

4. Beverage Stains

Beverage stains are yellow, tan, or brown stains that mysteriously appear on a garment after dry cleaning. These stains typically originate from accidental contact with soft drinks, tea, coffee, juices, beer, wine, fruits, candy, or any other food or beverage that contains sugar or tannin. After the moisture evaporates, an invisible residue remains. Over time, the residue, exposed to oxygen in the air, will oxidize, becoming yellowish and noticeable.

These types of stains are water-soluble and, thus, not readily removed by dry cleaning. The oxidation accelerates when heated during tumble drying or steam pressing, and the stain becomes much more visible. These types of stains can typically only be removed with special agents and procedures at a professional dry cleaner. However, after oxidation occurs, complete removal is very difficult.

Invisible Stain Prevention:

Our advice: The best short-term prevention is to thoroughly rinse all affected areas with water, taking care to blot and not rub the stained areas. That will get you through the night. Then, we advise you to bring the garment to the nearest professional dry cleaner as soon as possible to prevent any further damage or color loss. It is best to get the garment to us as soon as possible to prevent permanent damage or color loss. Make sure that the staff marks the stained areas for the best chance of partial removal.
