If your acetic acid solution is made in-house....I would suggest remaking it, just in case it was accidently made stronger.

However, last Friday, something happened and our H&E stains no longer look crisp, but instead have a hazy, unreadable look. Nothing different has been done, and we have troubleshot for every possible scenario. After a clean set up, we noticed that the hematoxylin is not staining very well. We have it set for 2 minutes with agitation for a uniform staining. Hematoxylin is Harris Special (mercury free) from MCC and the eosin is with phloxine b from AMT. After the hematoxylin (2 buckets for total of 4.5 minutes), we use 1.5% acetic acid. It seems that the hematoxylin is not staining well. Any tips? We may need to consider increasing a bucket for hematoxylin?
