My cleaning steps were as follows: (With correction to tubing size! I wrote the OD on accident on my previous thread.)
1. Get electrical contact cleaner; the cheapest generic brand is fine - Walmart carries it, Radioshack carries it for a bit more money, some gas stations carry it if you're lucky; but it should be really easy to find.
2. To clean the male end (with the pins) Hold it upside down, spray contact cleaner into it. It will evaporate very quickly; within 5 seconds. I used a toothpick, and an extremely thin cotton swab to scratch off gunk that was really fixated on there, and the cotton swab to clean up residue. Then, spray again with the cleaner, let it drip out and evaporate, and that was that. DO NOT use a lot of force in that area, the pins can break off easy if heavily corroded.
3. To clean the female end (harness end), I used the same contact cleaner, sprayed the harness, then stuck a sewing pin in each hole and scraped up and down to remove any gunk on the inside. Spray with contact cleaner again, then let it evaporate for a second.
4. Flipping the PSE upside down: Get 0.17" inner diameter tube (*I completely kept writing 1/4" ID without thinking twice; it was 1/4" Outer Diameter, 0.17" Inner Diameter. I apologize for that!)- Lowe's, Home depot, Autozone, O-reilly etc. carry this. It is cheap. I only used 2 ft. It's anywhere from 25cents to $1 a foot (depending on where you go.)
5. Cut however much you need (I used about 7" for each of the three vacuum hoses). The tubing should slide in easy, but very snug into the 0.17" inner diameter. I pushed it in about 1/2" on each end. Also; when you cut the vacuum hoses, cut with at least 3"-4" on the connecting side (don't splice it right by the connector, and not be able to insert the tubing into anything). And do it one at a time so there's no mix up. Then simply flip it upside down, reconnect everything, and stick it back in the foam box (it may fit a bit awkward, but it will fit). As for sealant, you won't honestly need it. It can't hurt, but it's not at all necessary. If you slide 1/2" of tubing into the 0.17" ID tube, nothing is going to happen or get into the hose unless you physically rip them out with a bit of force.
And that's all it takes. Nothing should cost more than $5, and it shouldn't take more than 15-20 minutes (and that's being careful).

Reason: CORRECTION TO TUBING SIZE! I meant to say 1/4" OD, 0.17" ID!
