We use the same specification steam cleaning technology as used inside a DOFF branded machine – which is the brand of stone cleaning machine authorized for use by English Heritage.
Stone is cleaned with less than 100 bar of pressure in conjunction with super heated water, heated to 150 degrees.
Chemicals are used for some projects, which again are safe for use on both brick and stone.
This all means that we don’t need to blast your building with super high pressure – steam cleaning does the heavy lifting, gently.
