Low Pressure, Superheated, Steam Cleaning

A data sheet on our Superheated Steam cleaning services, a suitable summary for printing is available in PDF format, Superheated Steam Leaflet; Stonehealth market their machine as DOFF(TM), and conservation officers often specify DOFF cleaning as a result. We don't actually use DOFF machines (we can do if you insist) but a competitor product called a Thermatec, but both machines generate superheated, low pressure steam at around 150 degrees centigrade, that is effective at cleaning stone and brick work, and providing a weed killing / mould killing and indeed sterilising surface treatment. In recent months we have used this machine in Lancashire (Bolton), Lincolnshire (Lincoln) and in central Nottingham.    

Although we specialise in using a listed building approved variable pressure sand jetting system which causes minimal damage to an underlying surface and is flexible enough to tackle most property restoration cleaning tasks.

That being so, there are times when using an abrasive system may be more than a substrate can cope with, and low pressure superheated steam may be the answer. It is generally slower, and less messy, and can be quite effective for surface contaminants such as algae and grime. Subsequent cleaning with the sand jet can remove stubborn stains.

 In Aberdeen we removed Litchen and moss (and grime) from the old Customs house almost in the centre of the city as it was converted from an office block to residential use.


Concrete Cleaning

This composting plant in Yorkshire needed something to clean the concrete walls, and ideally kill algae and bacteria in the process!
