Weird Splotches in Bag

[ksharp117]

Hello all 

Just had my first round of the season. While out I noticed these orange splotches inside my bag and am not sure what it is, is it mold? I remember them being there last summer. The bag is still pretty new. I stored the clubs in the basement in the box the bag came in, with the rain cover on. Did I store wrong. Anyways any ideas of what this could be?

Thanks.

If it’s mold, a mold removal clearer should clean it. Just wet a paper towel with the cleaner and dab the spot. If it doesn’t come out, it may be rust or other stain.

Possibly mold... But it could have been something that was spilled on it last year that did not react well to the conditions of storage. 

If it was new bag or stored in the original box with the cover on them, with no ventilation it's is possible that some VOC's reacted with whatever was on the bag. 

Kind of like that haze that forms on the inside of windshields no matter how much you clean it. It's the outgassing of VOC's from the materials in the cars interior. 

If it IS mold, as mentioned, a good mold/mildew spray will clean it up- but I would store it in a better environment. Basements can be notoriously damp, and without airflow that's a recipe for some really icky stuff to grow. Lucky it wasn't black mold.
