detergent. Other detergents may cause
oversudsing.

How much Detergent to use
The amount of detergent to use depends
on the water hardness. Water hardness is
measured in grains per gallon. Using too little
detergent can result in poor cleaning and hard
water filming or spotting. Using too much
detergent in soft water can cause etching
to some glassware which is surface damage
that appears like a film but cannot be wiped
off. Your local water company, water softener
company or county extension agent can tell
you the water hardness in your area.
