Indications of obsessions (Pluto) with neat, clean, symmetry ( Virgo)(obsessive-compulsive behaviour - Pluto) / searching for ‘beautiful ideals’ ( 9th house and Neptune) in the chart. This is a bit of a collection I’m using to understand these type of thoughts and behaviours.
1. Venus-pluto
I think it has to be a combination of things, because while Cancer and Virgo - and to some extent Scorpio - are more prone to OCD, the need for ideal form is more to do with Taurus and Libra, especially when Uranus - or perhaps Aquarius - are strong. Saturn's need for control can also contribute to obsession.

Not sure how venus-pluto would relate with symmetry and cleanliness... Obsession with beauty, maybe. Still depends on the signs and houses.
I'd say Mercury with Saturn influences.
