To achieve the expected results and durability associated with Bilt Hamber's range of sealants and waxes it is necessary to properly clean the surfaces to be treated first. Bilt Hamber cleanser-fluid is the perfect product for this task, as it flushes the surface pores of painted finishes, removing former last step product residues and embedded grime with ease. Being naphtha-based, it's less harsh than its alcohol-based rivals, yet much more effective, as evidenced by its ability to dissolve tar spots. Moreover, because it doesn't flash off as quickly, it's also far nicer to use.
