[Histonet] Purple haze on H&E slides

It looks to me like the problem might be caused by inadequate dehydration after the eosin.  Add a 95 % after the eosin then 3 100 %'s then the Xylenes.  2 min. in all of these should be adequate.
Hope this helps

We are using the Leica Selectech brand. No additives to the waterbath. We are using xtra or superfrost slides. The protocol is as follows:
3 min xylene
3 min xylene
1 min 100% ETOH
2 min 100% ETOH
1 min 95% ETOH
1 min water rinse
4 min hematoxylin
2 min water rinse
15 sec acid alcohol
1 min water rinse
1.5 min bluing
1 min water rinse
1 min 95% ETOH
5 min eosin
30 sec 100% ETOH
1 min 100% ETOH
1 min 100% ETOH
1 min xylene
2 min xylene

Any suggestions on getting rid of this? I actually got rid of it at one point, but the medical director wasn't happy with the stain. I appreciate any suggestions from the histology world.
