Summary
Presoaking was the most effective means of facilitating soil removal. This can be accomplished either in a soak tank or by wetting down the potatoes in a bin 1 day before washing.
Increased efficiency of washing was also obtained by increasing the length of time in the washer and drying the adhering soil before washing. A drum washer was only slightly more effective than a soak tank when the same time interval was used for both.
Potatoes susceptible to injury were damaged by too rigid a washing process.
