I put together a little script that I'm including in most export action I run. It suppresses any error message dialogs and removes any paths (no matter the naming or amount of paths), alpha channels, layer comps & color samples. However removing guides are done as a separate step in the action.
Create the script and then record an action where you launch the script on a open document. You must have a path in the image when you record it, otherwise the script won't run and the script will not be recorded to the action. Then call the action with "Save & Close" from Automate -> Batch, should do it.
#target photoshop
var theImage = app.activeDocument;
// supress dialog windows
displayDialogs = DialogModes.NO
// delete paths
theImage.pathItems.removeAll();
// delete alphas
theImage.channels.removeAll();
// delete layercomps
theImage.layerComps.removeAll();
// delete color samplers
theImage.colorSamplers.removeAll();
