I have a wall that goes into a storage room in the garage. It is drywall with fiberglass insulation. I stored a gallon of Biokleen (Biokleen All Purpose Cleaner Super Concentrated, 128 oz) and it looks like there was a leak, where about a quart of it spilled against the drywall for the past 1-2 years. I just found it today and removed the Biokleen container, but now there are white spots all over the floor and against the bottom of the drywall. I fear mold. I tested it with a moisture monitor and the top of the drywall is 0% moisture, while the bottom hit 96-100% moisture.

What do I do? Should I cut the drywall out? How do I go about cleaning this? Will cleaning this cause mold spores to go all over the house? Should I open up the wall, remove all insulation within a 12" radius of the wet spot, spray Mold Control/white vinegar, then re-mud?

Any helpful advice or any tips on anything I should consider is much appreciated.

This is my first home :(.
