Fast-drying, non-dissolving cleaning agent designed for cleansing most types of mass-coloured PVC window frames, sills, cladding, panels and trims and a range of other plastics including PVC, PMMA, PC, SAN, and ABS. Product removes dust, adhesive residues of protective film, pencil and pen marks, rubber residues, fresh PU foam and fresh residues of sealant, tar, bitumen. TENACLEAN 20 contains an antistatic agent that effectively dissipates static charges on plastic surfaces, thereby mitigating the attraction of dust and other contaminants to the cleaned surfaces, particularly PVC window frames. TENACLEAN 20 can be used for post-treatment after using more dissolving cleaners (e.g. TENACLEAN 5 or TENACLEAN 10).
