So there is 1 product? Is that was dedicated means, or is there one family of products (mammalian vs yeast). I’m confused why you said it is dedicated, but have different equipment. Are there multiple various processing routes for the same product.
But if you have multiple product, you can determine the worst case product, and use that for cleaning validation. You need to defend which product is worst case (there are a number of ways to do this). Once you have determined that, then you can do cleaning validation on that product, with verification of the other products as well.
Also, even a dedicated facility needs to look at detergent, microbial build-up, and other aspects of cleaning a truly dedicated process, even though lot-to-lot carryover is less of a concern.
