In short: Three pieces in one San Mateo home, each needing a different method: a synthetic blue sectional, a cream sofa and a wool Persian rug with natural dyes. The rug is the one that dictates how carefully the day has to be planned.
The situation
A blue sectional in one room, a cream sofa in another, and between them a Persian rug — hand-woven wool, almost certainly natural dyes given the colour range.
Treating all three the same way would be a mistake. Synthetic upholstery tolerates a warm alkaline solution. Wool does not. Wool is a protein fibre: a solution that is too alkaline strips its natural lanolin and leaves it brittle, and natural dyes bleed if the pH and the temperature are not kept down.
What we did
- Rug tested before anything else. Dye-bleed test on every colour in the rug, in a corner, before any solution is committed to.
- Wool-safe chemistry on the rug. Neutral pH, cool water, light passes. Nothing that would strip lanolin or move dye.
- Standard extraction on the upholstery. The sectional and sofa cleaned with ordinary warm-water extraction, which neither needs nor benefits from wool chemistry.
- Rug dried flat with air movement. Groomed in the direction of the pile and dried flat, never folded or hung while damp.
The result
The Persian rug came up with its colours separated and distinct again, which is the whole point with a hand-knotted piece — soil flattens the contrast between dyes long before it makes the rug look dirty. No dye movement anywhere.
All three pieces in one visit. The rug was dry by the following morning.
Questions people ask about this job
Can Persian and wool rugs be cleaned at home?
Many can, with wool-safe chemistry and careful drying. But hand-knotted, antique or silk rugs, and any rug where a dye test shows colour movement, should go off site to be washed and dried flat under controlled conditions. We test before deciding, not after.
Why can't you use the same solution on wool as on a synthetic sofa?
Wool is a protein fibre with natural lanolin that gives it resilience. Strongly alkaline solutions strip that lanolin and leave the fibre brittle and prone to shedding. Wool needs a neutral pH and cooler water.
How do you know if a rug's dyes will bleed?
A dye test: a damp white cloth pressed to each colour in a hidden corner for a minute. If colour transfers, the rug needs a different process. It takes five minutes and prevents the one mistake on a rug that cannot be undone.
