How to use Expired C41 Colour Paper

[L'Image]

Hi Guys,
I have just discovered two boxes of 50m rolls of colour paper., that I forgot I had stored away.
The first one is a Kodak Ektacolor Plus N 50.8cm x 50m, and the second is a Fujicolor Crystal Archive MP 76.2cm x 50m.
The Kodak is probably about 20 years old and the Fuji at least 12years. I have tried printing on both and they have a pinkish base to them instead of the pure white.
I was wondering if anyone know what filtration I could use to flash these in order to get a nice workable print from these.

I haven't seen pink fog on RA4 paper, only tan/yellow. Kodak paper is light pink before processing though.
There's nothing you can do against the fog.

Thank You PE for the prompt response.
The darkroom I use has one of those processing machines that you feed the prints through and collect the dried print at the output. I therefore have no control on the chemistry in the machine.the rest of the print looks very crisp except for those pink whites, which is why I was wondering if there was a possible filtration that could just act as an opposite for the pink. I have had prints done for me by professional printers in the past where they have flashed the paper and managed to get these rather lovely pastel feels in the prints.??
I thought if it was possible to do something like that I could make the most of the paper and embrace the colour. I am loathe to throw away such expensive paper......

Thanks Koraks for the insight. Will have another go with the paper.

Mods there would appear to be a need to merge these two threads which are almost still identical but in the time honoured fashion of Photrio will start to diverge and confuse with valuable inputs on both, requiring wasteful checking on both threads for progress

It isn't particularly likely that a moderator will see a post like this.
It is much more helpful to "Report" a post from one of the duplicate threads, and explain the situation. Reports go to all the moderators.
I'll do that for this post.

Thanks Matt. I had largely and, it appears wrongly, assumed that the ever-present mod was always checking for potential problems in the same way that there was always a guard swinging the spotlight around the wall of Sing Sing to detect potential problems such as Cody Jarrett in White Heat or Neville Brand in Riot in Cell Block 11 .
