An Alexander Duckham degreasant called Adkerner 99, to facilitate the thorough cleaning of engines and chassis, should be applied in its neat form, liberally brushed on to dirty or oily surfaces and after being given time to penetrate, flushed off with water.
To remove compacted dirt, oil and grease from surfaces such as garage and factory floors, etc., the hest results will be obtained after applying the degreasant, by using a scraper to break up the surface and then using a stiff brush until the floor is visible; the degreasant and soil can then be flushed off with water.
Engineering components or machined parts should be immersed in neat Adkemet 99 and then rinsed with water.
