Eh, need to know what kind of fabric this is. 100% cotton? 100% polyester? Cotton/polyester blend? Rayon (god please let it not be rayon)?
It’s fleecewear? So it’s probably polyester? Whew. [sigh of relief]
Do another short wash/rinse cycle, no need to add soap, then do another full-term dryer cycle. Make sure the dryer’s lint filter is empty when you start. I have great faith in a dryer’s ability to remove fuzzy stuff (speaking as one who frequently finds that Other People have left Kleenex in their jeans pockets AGAIN. Other Very Immature People. Other Juvenile People Who Won’t Always Have Mom Around To Do Their Laundry For Them…)
Sorry for the mini-rant. Carry on.
If it’s polyester fleecewear we’re talking about, you can keep doing this until all the TP is gone. Rayon isn’t happy being tumble dried in the first place, is why I’m hoping it wasn’t rayon. And cotton gets worn down a little bit every time you run it through the machines.
