Humidifier

Just replaced my green foam humidifier with a new one about 10 days ago, charged it with 50/50 prop glycol solution well 10 days later there is that cotton type mold growing on it, I thought the prop glycol prevents this.

I would give serious thought to buying humidity beads and using them instead of that type of humidifier. Heartfelt brand has a very good reputation.

Mold grows when conditions are right - regardless of whether there is something present to inhibit the growth (such as a 50/50 prop glycol solution). Not sure what's going on, but obviously the conditions are right to grow mold on your foam humidification device.

As CptnBlues suggests - beads are the way to go if you really want to prevent mold on the humidification device. There's no way mold can live on the beads as they're shipped, and will only grow mold if some type of food (e.g. cellulose) is somehow added to the beads.

I also recommend using straight distilled water to charge the beads. Less chance of something going wrong than using plain old tap water or even a prop glycol solution.
