ABSTRACT:
A cleaning solution for paper making equipment includes a stabilized source of peroxide in combination with a glycol ether solvent system and an alcohol ethoxylate. The peroxide system can be hydrogen peroxide stabilized with a phosphonate such as HEDP. The glycol solvent system may be a propylene glycol ether such as dipropylene glycol methylether or tripropylene glycol methylether. This solution can be formulated with a pH from about 4 to about 12. This is used by recirculating it through a paper making equipment during a shut down procedure.
