Duplicate image in Photoshop
dust and scratches filter set to 500 to blur it out.
Usually here I use the healing tool to remove any blurred lighter outline of the object but here there was none.
unselect the duplicate layer open apply image under tools and select subtract. Select the background copy and you can set the offset to various values to suit - 25 worked here.
This technique basically creates a false flat and subtracts it.
