Confirm the origin
Open the icon URL directly and verify bytes, response headers, and any CDN cache status. If the origin is old, clearing the browser changes nothing.

Version carefully
For browser-only changes, a versioned filename is reliable. For Google Search, stable URLs are preferred, so update the content and allow recrawling instead of constantly rotating names.

Reset local state
Use a clean browser profile, hard reload the page, close pinned tabs, and remove/re-add home-screen shortcuts or installed PWAs when those surfaces are stale.

Identify which cache still owns the old bytes
Compare the source file, origin response, CDN response, service-worker cache, clean browser profile, existing profile, installed shortcut, and search result. The first layer showing old bytes is the place to intervene.
A query parameter may prove browser caching, but a versioned filename with updated markup is easier to operate when the CDN ignores queries or normalizes cache keys.
Refresh in a controlled order
Purge or revalidate the origin and CDN first, update service-worker caches next, then test a clean browser profile. Clear an existing profile only after proving new users receive the correct file.
Saved home-screen icons and search results have separate refresh cycles. Re-adding a shortcut or requesting a crawl may be necessary even when the live page and ordinary browser tab are already current.

Questions, answered
Does Ctrl/Cmd+Shift+R always clear favicons?+
No. Browsers may store icon data separately from the normal page cache.
Should I add a random query string each load?+
No. It defeats caching and creates unstable URLs.
