Can Cold Water Clean Dishes?

Can Cold Water Clean  Dishes?

This is for all the germ conscious  folks that  worry about using cold water to  clean.
John went  to visit his 90 year old grandfather in a  very secluded, rural area of                     Saskatchewan.                                 .
After  spending a great evening chatting the night  away, the  next morning John's grandfather              prepared breakfast  of bacon, eggs and toast.                                  

However,   John noticed a film like substance on his plate, and  questioned his grandfather          asking,
'Are  these plates clean?'
His  grandfather replied,
'They're  as clean as cold water can get  'em.
Just  you go ahead and finish your meal,  Sonny!'

For  lunch the old man made hamburgers.
Again, John was concerned about the  plates,
as his appeared to have tiny specks around the  edge that looked like dried egg and                                 asked, 'Are  you sure these plates are clean?'
Without looking up the old man said,
'I told you before, Sonny, those dishes are as clean  as cold water can get them. Now don't               you fret, I don't want to hear another word about  it!'
Later that afternoon, John was on his way to a nearby town and as he was leaving, his grandfather's     dog started  to growl, and wouldn't let him pass.
                                                                   
John  yelled and said, 'Grandfather, your dog won't let me get to my car'.


Without diverting his attention from the football game he was watching on TV, the old man                 shouted! 'Coldwater, go lay down now, yah hear  me!'
