My strops only see the palm of my hand before and after shaving, I have one beater with a pasted linen that has been treated with Fromm dressing but I would never think to add this to my Kanayama or Spanish or English Bridle strops, I added it to an oil tanned strop one time and the draw became so heavy it was almost unusable and what I added was very little, what I have done once or twice over the last few years was after shaving I rinse my brush as most do and then apply my WH and splash and the very last thing I did was palm rubbed my strop before putting my razor to it before putting it away, I am sure some of the oils that are in the WH and splash along with the soap were on my hands and transferred to the strop, I am sure it's not that much oil but enough and I figure if I do this once or twice a year it will keep my strops is perfect shape for years to come.
