How much detergent to use
The amount of detergent to use depends on the
hardness of your water and the type of detergent. If you
use too little, dishes won't be clean. If you use too
much in soft water, glassware will etch.
Water hardness can change over a period of time. Find
out your water's hardness by asking your local water
department, water softener company, or county
extension agent.
Different brands of dishwasher detergent have different
amounts of phosphorous for softening water. If you
have hard water and use a detergent with a
phosphorous content of less than 8.7%, you might
need to use more detergent, or use a detergent with a
phosphorous content higher than 8.7%.
