    Hypo eliminators were recommended in the past, But are not considered advisable to use any more (by Kodak and others), as their aggressive action may harm paper and image silver.

    Hypo eliminator is not advisable for use with todays photographic materials and processing work flows. Hydrogen Peroxide is a strong oxidizing agent and it's only safe use is for cleaning lab working areas.

    Washing aids like Kodak HCA and Permawash or 20 grams of sodium sulfite in a liter of water are safe to use, but are not necessary if you are fixing with TF-4 or another comparable alkaline or neutral Rapid Fixer.
