Hi Lalith,
Anodised aluminium and other alloys used for rigid sterilisation containers, instrument graphic trays and some coloured anodised RMDs themselves are susceptible to extremes of pH. Some titanium compounds are used to give a matte dark finish on RMDS and these can be affected too. Washer-disinfectors that use a high alkaline detergent with corresponding acidic neutraliser, or an acidic rinse aid, can cause a number of surface changes including loss of colour, a sort of multicoloured, opalescent pattern and in the case of aluminium, a powdery feel to the finish. These tend to be beyond recovery.
It’s possible that a chemical product from the W-D has pooled or been allowed to stay on the tins for an abnormal time or that rinsing was impeded in some way, perhaps by the other contents in the load. Patterns of the discolouration may point you towards a particular cause. A service of the W-D and a review of loading patterns and practices may help.
Regards,
Andrew Ellis

Any thoughts on whats causing it would be much appreciated.
They go through the WD first then packed and sterilised in the autoclave.
Thank you
