Will there by any odours while having my carpets cleaned?
A simple carpet clean shouldn’t leave or cause any odours.
Spills in a carpet, however, may cause odours during their removal, milk, urine, and similar.
Some wool carpets may have a damp wet wool odour during clean but once they’re dry that odour’s usually gone. Some strong solutions used may have odours while in use but gone again when dry. DIY machines,they can over-wet the carpet, causing drying problems which can lead to strong odours of mould and mildew forming.
We would advise if you have any allergies or asthmas, inform the cleaning company so they can advise you of any potential odours and issues you may have.
