The London Eye has been a fixture on our skyline since the turn of the Millennium and not once in that period has it had a full clean - until now.
Glen Goodman reports.
The team who are cleaning the London Eye are no strangers to tackling some of the world's most iconic landmarks.
These pictures of the London Eye cleaning were taken by a camera attached to a model helicopter. A team was using steam cleaning apparatus on the centre of the Eye.
A team of cleaners, complete with abseiling equipment, climbed up the London Eye during the night to start giving it a clean. The project will take three weeks and is being done by the cleaning firm Karcher.
The team will clean two or three capsules each night, removing the thirteen years of grime that has built up since the Eye started operating. However during the day, the Eye will operate as normal.
Video footage from the television production company shows onlookers gasping as the daredevil's straight-jacket appeared to catch fire.
With just seconds to spare, he threw his jacket to the ground - to rounds of applause from those watching below.
The stunt was shot for the new show The Incredible Mr. Goodwin shown on TV Channel, Watch.
Last night 500 single people dated on the London Eye in 32 different dating experiences - London's biggest ever dating event.
Some capsules were turned into petting zoos with 50 rabbits, others turned into karaoke and cinema rooms. Some had ping pong tables and comedians entertained daters in others.
One capsule even offered people the chance to hop on single and get off married.
The London Eye was lit up in red and white last night to celebrate the 25th birthday of Where's Wally - the star of the puzzle books written by Hampstead author Martin Handford.
