A commercial deep clean covers all areas that routine daily cleaning does not reach: inside appliances, behind and underneath furniture, carpet extraction, hard floor machine scrubbing, descaling of washroom fixtures, cleaning of air vents and extractor fans, and thorough sanitisation of all touch points and surfaces. We tailor the scope to your premises.
