Merida heavy duty cleanesr are ideal solution in all places, for example, car workshops, where we deal with heavily soiled hands. Our heavy-duty cleaners remove even the toughest dirt. For instance, MECHANIK heavy-duty cleaner removes all dirt caused by graphite greases, engine oils, etc., and the lanolin derivatives and natural citrus oils in the cleaner prevent the skin from drying out even when washing hands frequently. The advantage of our heavy-duty cleaners is that the paste does not clog the sewage system, and its ingredients are biodegradable. Our heavy-duty cleaners are dermatologically tested.
