White Spots on Negs

[DH_Studio]

Hey everyone.

I processed some C41, scanned and had a few negs covered with these spots. I thought it was dust so I removed the carrier, cleaned the glass, blew it out, then blew the neg off and rescanned and all the spots are in the exact same place, so it definitely isn't dust. I took the neg back out and tried to rub off whatever the residue might be with a Pec Pad, blew it off, blew out the scanner, scanned again and again the spots were in the exact same place.

Is this water residue or stabilizer that didn't run all the way off? Or is this a processing mistake?

I used an Arista C41 kit. One minute prewash with agitation, then Developer, agitated first 10 seconds then every 30 seconds, same agitation with the blix (6.5 minutes), then washed for 3 minutes, then used the stabilizer (one minute with agitation first 15 seconds) and hung to dry. Used my finger as a squeegee, didn't notice any bubbles or stabilizer left over.

Is this a flatbed scanner? It looks a lot like dust on the bottom side of the glass. Do these marks actually show up on the negative if you examine it with a loupe on a light table?

can you post a photo of your strip of negs, something like this.

I opened the scanner and cleaned the bottom of both panes, scanning again today. I use an Epson v700 and the bottom was clean but there was dust on the inside of the top pane of glass, wonder if that was the issue. That one I'd never taken apart and cleaned, have only done the bottom. Not sure which side the camera's on with the v700 so hopefully that was it.
