Ellemby can now offer you an efficient solution to your specialist stonework cleaning needs. The DOFF cleaning system is quite literally like no other. Having used professional grade pressure washers for years and still not being able to remove lichen from stonework satisfactorily, trying every cleaning solution on the market we became frustrated at not being able to remove these ghastly black spots effectively.
Being asked by many clients how best to remove lichen growth from their driveway and patio areas we decided to research into what systems were out there. After much trial and error we decided to invest in and operate the DOFF system. Not only is the DOFF system amazing for cleaning lichen it also has many other uses. We were recently contracted to clean a Town Centre High Street which had years of dirty build up and of course many thousands of chewing gum deposits stuck to the pavement. The DOFF system made cleaning these areas much easier, removing a piece of ground in chewing gum in approximately 7 seconds.
Over time, any porous stonework will gather moss, algae, fungi and other biological matter which will make the building appear dirty. In order to restore stone to its former glory, DOFF Cleaning is used to clear away all foreign substances leaving the surfaces clean and bright. DOFF cleaning is also effective in cleaning and removing graffiti, bird fouling and oil.
On top of being a professional recognised method of cleaning utilised in Historic Building Conservation and Restoration Industry, Commercial sectors such as Local Authorities, Construction and Agriculture use the super heated steam based DOFF cleaning for best quality results ensuring environmental and hygiene standards are maintained.
