Does anyone distill mobile ACN and MeOH mobile phase solvents to imporve purity and reduce background?

We intermittently (but quite often it feels) have issues with batches of acetonitrile and methanol (LC-MS grade) with impurities either causing background, or causing ion suppression. This can cause operational delays until we find a batch that is suitable.

Wondering if anyone distills and whether it would assist.
