### Mr. Wayne Morris 

### AllAM 701 Pennsylvania Avenue, N.W. Suite 900 Wasbington, DC 20004 DearMr. Morris: This is to follow up on yourrequest from the Association ofRameAppliance Manufaeturers (AllAM) for infonnation on the number ofdishwasher cycles used, and pre-rinsinglpre.washing practices. The Soap and Detergent Association has approached its members who produce automatic dishwashing detergent to see 

### ifthis type ofdata exists. One company has responded 

### with the following information. Relative to the number ofautomatic dishwashing 

### toads done: \( .X

### 4.1 5,0 aU ADW owning households Relative to pre-treating, based on a 1995 consumer questionnaire study, this company reports that the percentage ofpeople who pretreated was 79%, Pre.trcating is defined as using water to rinse. scrub, or 

### soak. The remaining 21% did nothing or scraped offthe 

### plates without using water. As machine and product manufacturers advertise more Unproved cleaning**p~** 

### this 

### may decrease in the future. The company responding cautioned that the information is based on interviews with**consum~** and therefore is the individual consumer'$perception ofthe number ofloads tun. how many loads are pretreated. etc, The consumer's perception may notrepresentthe real number ofloads washed when measured in another objective measure ofloads washed. Because this is based on consumer perCeption and consumer'interpretation and bas the associated inherent uncertainties ofconsumer questionnaires. this data should probably not be used in an energy standards setting framework. The data. can give an indication ofthe use and patterns ofuse and may be useful to the DOE testing procedure. The members ofthe Soap and Detergent Association presents this infonnation based on this specific request. subjectto the comments above. We cannot guarantee that such data will be available in the future 

### or, if

### available, on whattime
