Started ruined?

Lads (and ladies)

I was making a wlp090 starter this morning, had a nice amount of harvested yeast and about 1.5 litres of wort.

I aerated it using my air stone which has a filter on it but never noticed a scummy green liquid in the line near the stone- it must have gotten in there during my last brew.

I soaked the stone and line in star San, and ran it for 20 mins in the starter flask (so was bubbling into sanitiser). Assuming most of the initial scum was sanitised initially, what are the chances do you think
that the yeast will outcompete whatever was in there left and that I'll have a usable starter?

Starsan isn't  a cleaner it's a sanitiser, a swill in w5 or pbw and rinse then quick bubble through starsan
I've seen folks boiling them.
Btw you don't need to aerate starters a good stirplate is all you want
