Our cleaning solution will remove some but not all the oxidation. The technique we use is called "soft washing." Soft washing is a little stronger pressure than a garden hose and can reach 2 1/2 - 3 stories high. We can demonstrate putting our hand in front of a soft washing nozzle without damage to our skin. Our methods help prevent oxidation while providing superior clean safety. We offer oxidation restoration services but prefer to save you money and the heartache of the expense.
