Scum Fighting on the kitchen floor.

Today was clear and sunny, good day for drying. So, haul the kitchen table and chairs and stuff out on the deck.   Wash the dishes to empty the sink.  Fill sink with Pinesol & hot water.  Do floor with sponge mop.  Notice that a scrummy film stays on the floor.  Pinesol doesn't seem to have the sack to cut thru it.  End up on hands and knees with 409 and a Scotchbrite.  That cuts the scum but it's a lot of work.  Wet mop after scrubbing and the rinse water comes out pitch black, so at least the dirt is coming up.  Four changes of rinse water and it's still coming out black.  But the floor is cleaner, and a shot of mop & glow and it's not too bad.  Dunno if it measures up to my Mother's standards, but it's good enough for me. 
   The world needs a better scum fighter.  Something that will cut the scum with just a sponge mop.
