The pressure’s been offset thanks to our Specialist team’s Grimebuster
29 February 2024
PRINCIPLE HAS taken delivery of a new machine - the Grimebuster.

Completely bespoke to Principle, the machine has already successfully resolved two major and particularly stubborn paint clean ups – as a result of protest action – and a number of periodic cleans.
According to Principle it’s twice as powerful as an industrial pressure washer at 10,000 psi and contains a boiler that heats up to 120°c, meaning it’s suitable for any floor type and no cleaning request is beyond our specialist team’s capability. Also, the safety of the team, clients and members of the public is a priority so not requiring electricity to function – and therefore no risk of harm to anyone – is of huge importance.
The machine will be out and about more on the streets of London, so if you have a particularly tricky cleaning issue that you need taking care of get in touch with Principle's specialist team.
