Clear all swatches in Photoshop

Can someone tell me if there is a way to clear all swatches at once instead of deleting them one at a time? I thought there was, but I can’t find it now.

Thanks

  1. “Reset Swatches” from pull-down menu in the “Swatches” tab
  2. In “Preset Manager/Swatches” select the first one, shift click on the last one and select “Delete”. You can also ctrl+click on single swatches to select/deselect (add to/subtract from selection)
