Fr. Buick Posted January 7, 2021 Share Posted January 7, 2021 Douse it with BP Blaster daily for a few days, then hit it with steam from a steam cleaner with a long wand. Wipe down, repeat as needed. Link to comment Share on other sites More sharing options...

Terry Wiegand Posted January 7, 2021 Share Posted January 7, 2021 Are you talking about the external surfaces on the block, or are you referring to the water jacket? Terry Wiegand South Hutchinson, Kansas Link to comment Share on other sites More sharing options...
