Washing is done with an alkaline washing agent, which, in use solution, has pH between 8.5 and 11. Rinsing is done with an acid rinsing agent, which contains hydrogen peroxide and, in use solution, has pH between 2.5 and 6. pH is stabilized by a weak acid or acid mixture that buffers so that pH during the rinsing does no rise above 7.
