Does any else routinely clean their single patient RO membranes?

Ours are heat cycled regularly, and chemically sanistised in the event of a poor microbiological sample result.

As part of a 12 month service the membrane is acid / alkali cleaned. Additionally they're citric cleaned 3 monthly if fed from unsoftened water. This regime means we typically get 5+ years from a membrane.

Our usual supplier has let us down with chemicals. Can anyone recommend anything? Or is cleaning not cost effective? Should we just diolox as-and-when and see how long the membranes last?
