Upholstery, Carpet Care, Mould, Odour and Pest Control

Upholstery and soft-furnishing cleaning, carpet care and hot-water extraction, humidity and mould control, tracing and eliminating odours, and onboard pest prevention.

Two weeks alongside in a humid marina, boat closed up, AC on economy. You open the VIP for a pre-arrival check and it smells. There is a faint bloom on the leather headboard, the carpet feels cold and slightly damp underfoot, and the wardrobe smells of nothing you want a guest to smell.

Upholstery and soft furnishings

  • Identify the cleaning code first — many marine fabrics are solvent-clean (S) or water-clean (W) only, and cushions are foam-cored and slow to dry.
  • Vacuum with an upholstery head before any wet work. Wet dirt becomes a stain.
  • Test any product on a hidden seam. Watch for colour lift and for a ring at the edge of the treated area.
  • Clean the whole panel or cushion face, not a spot, to avoid a halo.
  • Dry with airflow. A cushion put back damp is tomorrow mould.
  • Curtains, blinds and loose covers go to professional cleaners; shrinkage and lining distortion are common with amateur washing.

Carpet care and extraction

Method Use for Watch
Vacuum (beater/brush) Daily and detail Slow passes; edges and under furniture
Dry compound / encapsulation Wool, sisal, quick turnaround Sisal must stay dry
Hot-water extraction Deep clean, wool and synthetics, planned windows Over-wetting; leaves latex backing and subfloor damp; needs long drying
Spotting Immediate spills Blot outside-in, never rub

Extraction is a deep-clean-window job: it needs pre-vacuum, pre-spray, correct pH for wool, a proper rinse pass and 12-24 hours of airflow. An over-wet carpet on a boat, in an enclosed steel or GRP space, is a guaranteed mould and odour problem.

Mould and humidity

  • Target roughly 45-60% relative humidity. Above about 70% for a sustained period, mould germinates.
  • Cold spots — hull sides behind wardrobes, lockers against the shell, under mattresses on solid bases — condense first. Leave air gaps, use slatted bases, run dehumidifiers in layup.
  • Clean visible mould with the approved biocide and correct PPE, then fix the moisture source. Killing the bloom without curing the damp just delays it.
  • Never seal a wet space "to keep the smell in".

Odour

Odour is information. Trace it — do not mask it.

  • Common sources: grey and black water traps, dry shower drains, bilges, fridge drip trays, laundry drums, wet lockers, food in cabins, smoking on balconies.
  • Fix the source, ventilate, then use approved neutralisers rather than heavy fragrance. Guests notice cover-up scent instantly.

Pest control

  • Prevention: rigorous stores inspection at the passerelle, no cardboard aboard (roach eggs travel in corrugations), sealed dry goods, crumb discipline, hawser rat guards.
  • Record any sighting. One cockroach is a report, not a private problem.
  • Treatment is by licensed contractors; log chemicals used and keep the certificate.

Onboard Notes

  • Do not deploy a steam cleaner near veneers, lacquer, leather or headlining. Heat and moisture lift finishes.
  • Sisal and water do not mix — including in an "emergency".
  • If a cabin smells and you cannot find the source in ten minutes, escalate. Musty smells frequently mean a leak, a failed condensate drain or standing water someone else needs to fix.
