Spencer,
What was the alcohol percentage of the kind you used? Some is mostly water. Did you removed the LB completely, or just washed/dried what you could see with the bottom off??
Liquid damage is most often immediate and progressive.
You should get you laptop to a full service shop that can provide full testing and diagnostics. Troubleshooting this type of issue from liquid damage—on your own —will be expensive and time consuming, at best.
That said, try the least expensive part first.
