Why do my MF cloths leave fine 'hairs' behind?

[Tel]

I enjoy spending hours hand layering up Zymol concours on my motor. However I also do a lot of dry cleaning as well.

Before and after a drive I usually give it a once over with a spray of Dodo Supernatural Carnuba onto my Purple monster MF's. I bought these on recommendation.
I wash, as best I can the MF's on their own, with just washing gel and nothing else then dry them in the tumble drier.

Sometimes they leave behind what appears to be fine hairs around 3-4mm long, which I think could be lint where my cloths may have got into the kids wash or something.
I'm not sure, it's just a hunch, but are there any other explanations? and if so, how do I rid get rid?


Also I find these MF's hard work, i.e they seem very 'grabby'. Is it me getting old or have I made a poor choice of cloth/QD spray I wonder?
Interestingly, I find it a little easier having tried an Auto Finesse QD...any thoughts?

Cheap MF cloths from the 99p shop are all you ever need. Costco do a bundle that probably work out even cheaper but without the ziplock bags.

Cycle them so older cloths are used for initial wax removal and newer ones for a second wipe.

By all means wash them but only for use as hand towels or polishing tyre shine.
