We've had these issues too. Newer plastics don't seem to suffer, but older ones can be badly affected. it seems that any chlorine-based wipes cause the trouble.
Our Infection Prevention team have decreed that we have to carry on using them nevertheless.
Having tried the "joined up thinking" approach and actually meeting with the IP team and end users I think we may have made some headway against these apparently widespread ritualistic dictates!
Our currently imposed Clinell wipes contain the dreaded benzalkonium. We were able to show the IPC Team a device showing surface damage that was purchased after these wipes became the default technique.
Staff involved had already confirmed the machine has only ever been 'cleaned' using the wipes.
When we produced the manufacturers cleaning instructions showing the device has therefore been exposed to inappropriately harsh chemical 'attack' they readily conceded the cleaning regime needs urgent review!
The brief discussion that then followed drew the conclusion it may well be the case that we return to the days of warm soapy water and a damp cloth to actually clean dirty things and then only if actually indicated either 70%IPA or a sporicidal wipe if specific contamination is present.
How the carousel of healthcare turns.....
What we have found however is that as usual now we have seen the problem on a couple of devices it appears we are noticing it on others.
