Acid washing WY3711

After my last saison, I kept the yeast slurry and rinsed it until I had about 1/4 cup or so of creamy, fairly clean looking yeast.  This went into a Star-San rinsed plastic vial (new, not a WLP vial) and into the fridge.  It’s been in there for a month or so now.

There’s nothing odd looking about it but I’m wondering if this would benefit from some additional washing?  I’m not sure when I will brew a saison again, probably after the new year to start building up summer beers. 
Does anyone do this?  Yes, I know it is cheap enough to buy a new pack but where’s the fun in that?  If it was about being easy, I’d buy beer.  I like the learning and the challenge. Thoughts?
Thanks.

I would leave it as is and just burp it every couple of weeks.

From you description, no need to wash again but it would benefit from a starter when your ready to brew again.
