Aims: Liquid dish washing solution (DWS) was used as a substitute for xylene to dewax tissue sections during hematoxylin and eosin (H and E) staining. The aim was to test and compare the hypothesis that xylene-ethanol free (XEF) sections deparaffinized with diluted DWS are better than or at par with the conventional H and E sections. Materials and Methods: Fifty paraffin-embedded tissue blocks was included. One section was stained with conventional HandE (group A) and the other with XEF HandE (group B) staining method. Slides were scored for parameters: nuclear, cytoplasmic, clarity, uniformity, and crispness of staining. Z test was used for statistical analysis. For accuracy of diagnosis, sensitivity, specificity, positive predictive value, and negative predictive value were tested. Results: Adequate nuclear staining was noted in 94% in group A and 96% in group B, -adequate cytoplasmic staining in 92% in group A and 86% in group B, clarity in 94% of group A and 96% of group B sections, uniform staining in 92% of group A and 80% of group B sections, crisp stain in 96% of group A and 88% of group B sections, and 94% of group A sections stained adequately for diagnosis as compared with 90% in group B sections. Conclusion: Liquid DWS can be used as an alternative and effective substitute to xylene and ethanol in routine HandE staining procedure
