Just wash it, and pretend it isn't there
It's not a problem.
It will either die over time, or it won't. Either way is good
Once the rind gets older, if you still have geo it will be beneficial and give you a nice white dusting
The idea with a washed rind, in theory, is to isolate wild bacteria. In reality we get a lot more than just bacteria. Geo is one thing we often get, it's no problem.
My cheese tends to get geo on it, and sometimes it makes the rind a little wrinkly. But I like the added depth of flavor it adds. Straight up linens can be a little.. unpleasant but when we add diversity of other cultures it's actually quite nice.
