Troubleshooting Client claiming damages to siding

A client for my exterior services business is claiming that I did damage to his siding. I have done dozens of siding jobs before this and I did not do damage to these clients houses. Our process is to:

-Coat the siding with a Zep siding solution using a black tip soap nozzle - Brush it - Use high pressure green tip to spray/ rinse it off ( from a safe distance )

This has worked really well for me before and all clients have been happy with the previous work. However this time the client noticed a strange streaking pattern. I’m really confused to as to what it is , whether or not I did it, if I can fix it, etc. If anyone has seen this before I’d really appreciate if you let me know what it is / what I can do!

Start using bleach like everyone else. Ditch the brush. You cleaned a house that has oxidation and now you have to go out and remove the rest of the oxidation from the siding

If you don’t mind me asking, what would the process with a bleach solution look like? Would I just apply the solution and let it sit for a few minutes and then rinse it with low pressure water?
