With New Year traditionally being the time to make a start on some serious house-cleaning, a team of conservation cleaners are hard at work at Blenheim Palace.

The palace has been getting a 'deep clean' - a painstaking procedure that has been taking place each year since it first opened its doors to visitors in 1950.

As part of the process, Blenheim is running twice-daily tours on selected dates throughout January and February to provide the public with an insight into what it takes to keep a stately home looking its best.

Visitors can pick up some top housekeeping tips from the experts.

Although the techniques, equipment and conservation procedures have changed over the decades, the cleaning process itself still takes six weeks with a team of up to six people working daily.

“Each room has to be carefully stripped of all the furniture and artefacts and vacuumed from floor to ceiling,” said Carmen Alvarez, deputy collections manager at Blenheim Palace.

“The floors are then cleaned and polished. Whilst this is taking place, the rest of the team inspect and assess each item before it is returned to the room.

“We use a variety of tools from museum vacuum cleaners with HEPA filters to natural bristle brushes such as hogs’ hair or goats’ hair, depending on the object we are cleaning.

“Polishes are kept to a minimum, as they can build up over time and we do not use aerosol sprays. Stubborn dirt is removed by distilled water,” she added.

The Oxfordshire UNESCO World Heritage Site houses one of the most important and extensive collections in Europe, which includes portraits, furniture, sculptures, and tapestries.

Specific items being cleaned include: 40 busts and sculptures, 28 marble tables, 10,000 books, 18 clocks, 38 pieces of armour and 200 pieces of porcelain.

Tours are running twice a day until January 16 and then again from February 7 to 18.

The tours are included as part of the admission, take place at midday and 2pm, and last for around 45 minutes.

Home to the Dukes of Marlborough since 1704, Blenheim was designated a UNESCO World Heritage Site in 1987.

Set in over 2,000 acres of ‘Capability’ Brown landscaped parkland and designed by Vanbrugh in the Baroque style, it was financed by Queen Anne, on behalf of a grateful nation, following the first Duke of Marlborough’s triumph over the French in the War of the Spanish Succession.

This year is the 300th anniversary of the 1st Duke’s death and it is being marked by a series of special events and exhibitions.
