The unique formulation of the Calotherm Microfibre Cloth far exceeds any conventional cloth and enables grease, dirt and moisture to be removed from the most sophisticated of coatings. The knitted fabric is produced with a higher concentration of fibres than any other cloth It is then chemically treated to split the fibres, making them finer The split fibres give even greater fibre concentration with air pockets to lift and hold dirt and grease away from any surface.
