Can cold water clean dishes?

Happy Camper!
A man went to visit his 90-year-old grandfather in a very secluded rural
area of the state he lived in.

After spending the night, his grandfather prepared breakfast for him
consisting of eggs and bacon. He noticed a film like substance on his
plate and he questioned his grandfather, "Are these plates clean?"

His grandfather replied, "Those plates are as clean as cold water can
get them, so go on and finish your meal".

That afternoon, while eating the hamburgers his grandfather made for
lunch, he noticed tiny specks around the edge of his plate and a
substance that looked like dried egg yokes...so he asked again, "Are you sure these plates are clean"?

Without looking up from his hamburger, the grandfather says, "I told you
before; those dishes are as clean as cold water can get them. Now
don't ask me about it anymore!"

As he was leaving, his grandfather's dog started to growl and wouldn't
let him pass so he said, "Grandfather, your dog won't let me out".

Without diverting his attention from the football game he was watching
on tv, his grandfather shouted, "Cold Water, go lie down!"
