Removing Calcitriol Residue

Hi All, First post so apologies if I've done anything wrong. I did a search for similar topics but couldn't find anything. I currently use Silkis calcitriol ointment on my genital area for mild Psoriasis. I apply this at night time and it does work, however the issue is the next day. It can be difficult to remove remaining residues and due to the sensitivity of the area I'm wary of using any harsh chemicals. Does anyone have any recommendations for products I could use for this?
