Is it okay to machine dry Fuzzi Bunz?

I dry mine after every use with the rest of my diapers and I've had no problems. You should be okay.

lint balls. I know mine did.

While I usually line dry, I occasionally put them in the dryer if I need them NOW. I've had no problems. It is true that they dry REALLY quickly on the line.

I've gotten lazy and started sticking them in the dryer too. I've been doing this for the past 2-3 months without any problems.

I only line dry my fb's. I have gotten 2 fbs on the trader from someone who dryer dried them, and you can most certainly tell the difference. They are hard and scratchy, and I ended up putting them in my vehicle for emergency diaper use. I HATE them.
so, if you want them to last a little longer, and remain nice and soft, just dry them the first or second time, and line them the other times.....this is my experience. Someone may have a different thing happen to them.

I always dried mine with no problems

I read that you should line dry them but occasionally put PUL in the dryer to "reseal". Of course, i have no idea where i read that b/c all i seem to do these days is read about diapers on a million different sites!!!

I dried them the 2 times recommended and now I line dry. I have a line set up by my drier, so I wash my inserts and washcloths and fitteds together, and dry them in the drier, then I wash all FB's and PUL covers in the wash and hang to dry. They usually are done around the time the inserts are done. Fleece dries quick

If your dryer has a low heat setting, it should be fine. We've never had one wear out in 2+ years.
