Processen kan inte förhindras, bara fördröjas. Om filmerna förvaras enligt rekommendationer i kall och torr miljö har den förväntade livslängden på filmerna beräknats till omkring 400 år. Studier vid Institute of Sustainable Heritage, UCL, har nu visat att det snarare dröjer 70 år innan vinägersyndromet sätter in. Åtgärder för att säkra filmerna eller fördröja processen är sänka lagringstemperaturen, minska fuktigheten, sätta i karantän de filmer som visar symptom på vinägersyndrom (filmerna kan ”smitta” andra filmer), göra ny kopia av filmerna eller föra över dem till digital miljö.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-reference-link-bracket">[</span>2<span class="cite-reference-link-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Se_även"><span id="Se_.C3.A4ven"></span>Se även</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Fotografisk_film&veaction=edit&section=3" title="Redigera avsnitt: Se även" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Fotografisk_film&action=edit&section=3" title="Redigera avsnitts källkod: Se även"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Framkallning" title="Framkallning">Framkallning</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="Referenser">Referenser</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Fotografisk_film&veaction=edit&section=4" title="Redigera avsnitt: Referenser" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Fotografisk_film&action=edit&section=4" title="Redigera avsnitts källkod: Referenser"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><a href="#cite_ref-1">^</a> <span class="reference-text"><cite style="font-style:normal" class="web"><a rel="nofollow" class="external text" href="https://web.archive.org/web/20160402204359/https://www.solna.se/templates/page_solna_submenu.aspx?id=19492">”Solna stad : <i>Filmstaden</i>”</a>.
