Pine Needles in Microfiber Cloth—Discard

[PianoAl]

Occasionally, I drop one of the microfiber cloths I use when washing the car. It instantly gets tiny pine needles embedded in it.

Will these scratch the finish?

It's very hard to remove them, so I might just discard the cloths that are dirty.

Yea I’d discard. But first use it for something super dirty like tires or wheel wells.

I’d use it as a shop rag.

Agreed on not discarding but only using on non-important things.

Or, go full OCD, and pick ‘em all out!

For the low price of MF towels at COSTCO it's not worth the risk using on the car - but another pack.
I will use dropped/filthy MF for general rags until they give up the ghost.
