qgis - Removing narrow polygon dangles?

Using QGIS v 3.4.4.

I have a polygon layer in which some shapes have a very narrow extension that i would like to remove. Unless zoomed in these extensions appear as dangles but when zoomed right in you can see that they are part of the polygon shape. I have tried the v.clean toolset without success and snap geometries to layer which ends up crashing the project. I can manually edit the shape to correct but I don't know how many or where these occur in the layer.
