Grit in roller train

Good day fellow printers,

I have been having a problem lately with a lot of grit in my roller train. I have tried washing it out but have not been very successful. I could do a Calcium slayer and hot water rinse every evening just to try to stay after it.

Has anyone seen this before? We are switching from pacesetter rollers to boettcher and it's on both brands of rollers and in every unit. Currently we are running a toyo medium tack ink and a prisco one step fountain solution with alkaless 6000 added. It's an 8 color 106xl press. Here are a couple of photos.

Thank you for your help
