Dried ONR in MF towel

[C5Longhorn]

Any harm in letting a MF towel saturated in ONR dry? I've been doing rinseless washes and wondered if I can let the towels dry before I accumulate a batch and wash.

I do the same and no issues. What I prefer to do though is just let them soak in more onr solution. The dirt release on onr soaked wash medium is quite great.
