I'm laughing with you... naaa... I'm laughing at you.
Take the previous suggestions seriously. It's corrosive to our old wiring. If it were me, this is what I'd do:
1. Vaccum out as much as I could.
2. Drape a blanket over the engine compartment, and then used compressed air to blow out as much as I could.
3. Remove EVERYTHING from the rear trunk, and start cleaning it all meticulously. This means your ignition unit, the rear tail lights, everything.
4. Then clean the wiring harness like it was a surgical instrument.
5. Get some dielectric grease and coat all your connections.
6. Reassemble.
