During two harvest seasons, 103 drying wagon lots of Florunner peanuts were graded, cleaned and regraded. The effects of cleaning on grade parameters and economic value were evaluated. Observed value changes were compared to theoretical value changes assuming removal of all grade — indicated foreign material. Niether theoretical or experimental benefits of cleaning prior to marketing increased economic value enough to exceed to the current commercial charge for cleaning.
