I hope you're also using tableau web server to publish and share the viz with your clients. If so, then I would suggest you should educate your interactors to use |<--Revert option while visualising any dashboard to clear all the filters. This option you get once you publish your dashboard in tableau web server.
Let me know If you've any query.
I think there is no option to reset parameters on tableau desktop
This option will not work for us, as it also resets all the actions previously applied on the screen (Filter, dashboard actions). Is there any other way to only target the parameters.
