The staining looked unhygienic and we raised this with Tayside Contracts (which is responsible for the cleaning of the facility) querying if this was a cleaning issue or some form of further repair intervention is required to remove this.
We had a very prompt response from the Managing Director of Tayside Contracts as follows :
"Our cleaning team have reported that the power washer was faulty. This has now been rectified and we do not anticipate that this problem will recur."
