Universal Wipes are safe to be used on most non-porous surfaces. They will not damage rubbers, plastics or metals. Though alcohol-based wipes tend to damage materials after prolonged use, our patented, pH neutral formula ensures that this will not occur with Clinell Universal Wipes. Alongside surfaces, Universal Wipes can be used on all non-invasive medical devices. If you are unsure about whether the wipes are suitable to use on a particular object or surface please call a member of our sales team, who will be happy to assist. Always follow medical equipment manufacturer's cleaning procedures and guidelines
