Only use the following for cleaning gasket surfaces:

Plastic or wood scraper (Fig 1 )
Drill motor with 3M Roloc(tm) Bristle Disc (white or yellow) (Fig 1 )

CAUTION: Excessive pressure or high RPM (beyond the recommended speed), can damage the sealing surfaces. The mild (white, 120 grit) bristle disc is recommended. If necessary, the medium (yellow, 80 grit) bristle disc may be used on cast iron surfaces with care.
