The right technology every time

When considering the best way of cleaning away contamination, a distinction is made between organic substances – which include oils and greases – and inorganic residues such as salts and abraded or emulsion residues. In this context, there is truth in an old adage which says that: “Like dissolves like". What is meant by this is that organic contamination is most effectively removed by an organic solvent (hydrocarbons, modified alcohols, chlorinated solvents). Inorganic residues, conversely, are best removed using an inorganic aqueous based cleaning agent. If both kinds of contamination have to be tackled, then ideal results are achieved using combined systems (our BEYOND or HYBRID methods).
