That's likely not a dangerous kind of mold but when I come across mold in cars - barn finds - I put on a mask and gloves and try to wet it as much as possible without disturbing it - I want it dead before it gets airborne and I throw away the cloths I use and wash the brushes in bleach.

The chances of getting a mold infection are slim but the chances of it not being serious are even slimmer.
