Why Colors Bleed on Oriental Rugs

Why Do Colors Bleed on Oriental and Persian Rugs?

Color bleeding in Oriental and Persian rugs is a common but avoidable issue. Whether caused by pet urine, water damage, or improper cleaning, color migration can permanently stain or fade a rug.

At Oriental Rug Salon, we specialize in identifying and preventing dye bleed before any cleaning begins.

Let’s explain why this happens, what types of rugs are at risk, and how we protect your investment.

What Causes Dye Migration in Area Rugs?

Dye migration happens when water or moisture interacts with unstable dyes used in rug fibers. When exposed to liquids, these unstable dyes begin to dissolve and move into adjacent areas.

Most vulnerable are:

  • Hand-knotted rugs made with vegetable dyes
  • Antique or tribal village rugs
  • Rugs with bold red, blue, or black tones

The older or more artisanal the rug, the higher the chance that its dyes were never chemically fixed. Machine-made rugs typically use synthetic dyes, which are less prone to bleeding, but still not immune under extreme conditions.

Dye bleeding is often irreversible. That’s why professional rug cleaners must always test for dye stability before cleaning.

Why Pet Urine and Liquids Trigger Color Bleeding

Pet urine isn’t just a stain—it’s a chemical cocktail. It’s acidic when it’s fresh and becomes alkaline over time. That change in pH can break down natural dyes and loosen the bond between fiber and pigment.

When left untreated, urine soaks into the foundation and spreads the dyes, especially in wool-on-cotton rugs.

Even plain water from a spill, leak, or over-wetting by a steam cleaning company during cleaning can lead to color migration in rugs with unstable dyes.

Warning signs of dye migration:

  • Faded or blurred design lines
  • Smudged colors near dark borders
  • A pink or purple haze on lighter areas

Professional treatment is the only way to neutralize pet urine and stop the damage from spreading.

Vegetable Dyes and Antique Rugs: A Delicate Balance

Rugs dyed with natural plant-based pigments (like madder root, indigo, or pomegranate rind) are prized for their beauty—but notoriously unstable.

In many village-made rugs, the dyeing process is done by hand, without the use of chemical mordants to lock in color—the result is stunning hues that can shift or bleed when exposed to moisture or heat.

Antique rugs are particularly vulnerable:

Years of wear weaken the dye bonds

They are often stored or displayed in humid environments

They’re less likely to have ever been professionally cleaned

This doesn’t mean they can’t be cleaned—only that they need specialized care.

Our Colorfastness Testing Process

At Oriental Rug Salon, we test every rug before cleaning using industry-approved procedures.

We isolate each primary color in the rug and apply a solution to test for bleeding. This helps us:

  • Identify problem areas
  • Choose the safest cleaning solutions
  • Stabilize dyes before complete immersion cleaning

If bleeding is detected, we can apply fixatives to temporarily lock in the color. For rugs with unstable red or blue borders, we use a controlled drying and rinsing process to prevent migration.

General carpet cleaners or DIY methods rarely offer this level of controlled testing. It’s one of the reasons clients trust us with high-value textiles.

Emergency Situations: Floods, Pets, and Accidents

Many of the worst dye migration issues we treat aren’t caused by routine use—they’re the result of accidents.

Clients often contact us after:

  • A pet urinates on a cherished rug
  • A roof leak or flood saturates an antique runner
  • A pipe bursts in the attic or under the floor
  • A steam cleaning company tried to clean their cherished area rug using steam or other unapproved methods

In these moments, time is critical. The longer a rug stays wet, the more likely it is that dyes will run.

Fire Suppression and HVAC Leaks

When sprinklers or A/C systems leak, rugs absorb large amounts of water. If the rug is left sitting damp, mold and dye migration set in quickly.

Insurance and restoration companies frequently contact us to assess and attempt to restore these types of losses. Our dye testing and cleaning protocols are often the difference between saving or losing a treasured rug.

DIY Plumbing Disasters

We’ve also seen rugs damaged after a homeowner installs a water filter, fridge water line, or washer connection—only to have it burst and flood the house.

If you experience a leak, avoid using fans or heat on the rug. Call us immediately to minimize permanent color loss.
