How to clean the inside of an iPhone 4S

My iPhone got dropped in a sugary liquid, but only for a couple seconds. Since it was sugary, all of the side buttons and top button are now sticky and causing problems with the volume. Is there any way of opening the back and cleaning this so the buttons no longer stick? I even had a LifeProof cover on it but somehow it still got wet inside (I don't know how that happens?!). Apple is still insisting that I replace it and LifeProof doesn't cover the electronics inside their cases. Please help :(

If you have experience in fully disassembling the iPhone, you can get 92%+ alcohol, a small hobby/paint brush, jewelers loupe (20x) and an anti-static cloth. Power off the phone, remove the battery, then use the brush to gently brush on the alcohol, use the cloth to blot away any debris, and use your loupe to check where you cleaned. Don't scrub, just smoothly wipe the brush in a small section and blot, then check. It will take some time, but, with patience (and ensuring their is no current flowing) it can be cleaned and restored to working order, in most cases.
