We've had our active third-party stress-tested for corrosion on metals in accordance to our directions for use on premium quality stainless steel. Following our directions for use we do not cause pitting and rusting on high quality metals. However, there are a number of factors that can cause rusting that we cannot guarantee. These include: Low grade metal frames, albeit coated in titanium. Low quality titanium alloys or thin coating. High presence of soft metals such as aluminium in the material composition of the tools. Storing tools in humid environments that cause moisture. Poorly drying your tools post disinfection. Not rinsing actives off with water. Interactions between two different cleaning products can increase risk of rusting irrespective of the active used. Never combine two different cleaning products including wipes without rinsing off with water inbetween. These factors are relevant for the use of all cleaning actives including alcohol, bleach, blue disinfectants and hypochlorous. Some brands recommend the use of wipes to reduce the risk due to the lack of active on the wipe. However, this is problematic because wipes do not sufficiently disinfect tools in accordance to HABIA & HSE standards. This is why you will never see the use of wipes as a disinfection standard for tools in the food or medical industries. To avoid rusting opt for premium grade metal tools (we recommend grade 316 stainless steel which is highly resistant to corrosion and is a food and medical grade metal and/or true titanium); follow our tested and approved guidelines for use; and always rinse off with water before and after use.
