Prints processes in TF-5 don't require a wash aid unless you tone. If you tone legacy recommendations were to mix wash aid with the toner. However wash aid has a short life in mixed solution. KRST will have a longer life when mixed with water only. Avoid wasting good toner mixed in oxidized wash aid. The modern method is to fix prints in a neutral to alkaline fix (without harder) at film strength for 60s. Only use a hardener if hot glazing. Use the wash aid after toning for 10 min. Follow Ilford's optimum permanence directions. Ilford is now recommending toner mixed in wash aid but that may be to accommodate prints fixed in acid fixers. I don't experience stains when mixing KRST with water and following Ilford's optimum permanence recommendations.
