- The twelve-step Horizon hand-wash process.
- Persian, Turkish, French, silk — the rugs we hand-wash.
- The chemistry — dye stability, fiber, foundation.

How to Flatten a Rug (Creases and Curled Corners)
Many creases ease with time, a loose reverse-roll, spread weight and a pad, and no iron. A few do not, because the rug itself has changed shape, and that is a repair.
How to Get Coffee Out of a Rug
Black coffee and coffee with milk are two different stains, and a wool rug wants them handled in a different order. Blot, keep it cool, use detergent weak and vinegar second.
How to Get Vomit Out of a Rug
Vomit leaves three things in a rug: acid, protein and bile. Cool water, blotting and patience lift what can be lifted. Heat, bleach, baking soda and enzyme sprays each add a problem of their own.
How to Get Blood Out of a Rug
Blood is a protein stain, and heat is what sets it. Cold water, a white cloth pressed and lifted, a mild detergent for wool, and what to do once it has dried.
How to Get Gum Out of a Rug
Ice in a closed bag until the gum is hard, a rounded spoon to lift it, and a tested solvent for the film it leaves. Warm gum flows; cold gum does not.
How to Get Paint, Ink and Nail Polish Out of a Rug
Three accidents with one thing in common: the remedy many guides suggest is a solvent, and on a rug a solvent can move the rug's own dye along with the stain.
How to Get Slime Out of a Rug
Most answers online are written for wall-to-wall carpet. On a hand-knotted wool rug, vinegar in hot water can help set the dye instead of lifting it.

If a smell keeps returning, it was never removed - only covered. Where odor actually lives in a rug, why baking soda and sprays fail, and the wash that takes it out for good.

How to Clean a Chinese Rug
Chinese rugs are built and finished unlike any other - deep sculpted wool, a chemical sheen wash, and reds that run. What is safe to do at home, what sets a stain for good, and why a Chinese rug must be washed by hand.
How to Remove Color Bleed From a Rug
Color bleed is dye that has moved where it does not belong. What to do the moment you see it while the rug is still wet, what sets the stain for good, and when bled color becomes a restoration.
How to Clean an Area Rug Without Moving It
You can vacuum, refresh, and spot-treat an area rug where it lies, but you cannot wash it there. What is safe to do in place, what to never do on the floor, and when the rug has to be lifted.
Is Steam Cleaning Safe for a Persian Rug?
The short answer is no. Why heat and hot-water extraction felt the wool, bleed the vegetable dyes, and swell the foundation of a hand-knotted Persian rug, and what to do instead.

Pet urine is not a stain, it is chemistry that bonds to wool and dye as it dries. What to do in the first hour, the home remedies that make it worse, and when it needs the workshop.
