Upon arrival, we respect your home by placing waterproof sheets around the appliances to be cleaned to protect the floor coverings. Any removable parts are soaked in the specialist vehicle mounted heated tank while we get to work on your oven. The oven doors are removed to gain access to some of the more difficult to reach areas and where possible, doors will be split to allow cleaning between inner and outer glass panels. Should you require a bulb, we can replace it at the same time. Ovenclean4u are 100% committed to supplying value for money, superior quality oven cleaning and exceptional customer service.
