더라구요

Polite 'I found that...'

Reports something you discovered or witnessed yourself, politely: there's a bleach you can just spray on, my wife got worried, it was pretty edible, there are common features. The 더 part is the crucial bit — it means you saw or felt it personally, so it does not fit things you merely heard about. It is the relaxed spoken spelling of 더라고요, which is what you would write.

Register: polite, spoken
