Carpet stains that won't come out — Hilversum, Noord-Holland

Stubborn carpet stains — wine, coffee, pet urine, ink, or ground-in dirt — resist regular vacuuming and store-bought spot cleaners. Professional carpet cleaning uses hot water extraction at 200°F+ to dissolve and extract stains from deep within the carpet fibers and pad. Most stains that have set for less than 6 months respond well to professional treatment ($120–$300 for a whole-home clean, $50–$100 for targeted spot treatment). The longer a stain sits, the more it bonds to carpet fibers — treat quickly for best results. If the stain has reached the carpet pad (common with pet urine), the pad may need replacement along with cleaning for full odor removal.
