A friend tells me that there is a cleaning solution available which stands
overnight in sink drains to clear away grease build-up.

He also said that he had learned through some "tip sheet" that carbonated
soft drinks accomplish the same thing and are cheaper when you get them on
sale.

Is this correct?

just remembered...

kitchen of the private club in downtown San Jose, CA on the top floor
of the tallest building went for about one year before the grease
buildup in the drain systems caught up to them. Then the drains
clogged big time, backing up several 'lower' tenants' drains, visibly
running water down stairwell! - causing $1000's ++ damages the club
was liable for!

After that experience they started adding enzymes to the drains and
then have gone for over 15 years without another problem.

Don't know which product, but suspect it's well known among restarants
and pubs.
