Low risk
You are moving out, the inventory check is booked, and cleanliness is the thing most likely to cost you your deposit.
Caution
Black carbon on the oven floor and door glass that no spray or scrub has touched.
Black spots and streaks in the silicone around the bath and shower, and along the grout lines.
Chalky white crust on taps and shower heads, a cloudy screen, and a stubborn ring in the toilet.
Sticky amber film on the cupboard doors above the hob, and an extractor filter you have never taken out.
The work is finished, the dust sheets are gone, and there is a fine grey film on every surface in the house.
The drum smells stale, the rubber door seal has black spots, and clean washing comes out musty.
A carpet that looks acceptable but smells, or has marks that come back a few days after cleaning.
Marks and a stale smell on upholstery or a mattress, and no idea what is safe to put on it.
Black mould spreading on the window reveal, in the corner of a cold external wall, or behind a wardrobe.
Describe the job and get a fixed price from a local cleaner.
