Answers:
I wish you wouldn't tackle this job yourself, but I suspect you just don't have the money to have it done right now. You probably are not going to get a perfectly clean coil with a do-it-yourself project, but we can try to improve your existing condition.
Coil cleaner is caustic. It will burn your eyes and skin, so your list at Home Depot will include non-acid coil cleaner, (1 quart) plastic gloves, goggles, a flashlight and a Shop-Vac.
With the a/c t-stat and breakers switched off, spray the coil cleaner on the underside of the coil(the dirty side) liberally.Let it sit for at least thirty minutes until the crud starts oozing out. DO NOT brush, mash, poke or touch the coil fins in any way. Suck the goo off the floor and hit it again with coil cleaner. Repeat this same process until crud is no longer oozing and foam is no longer foaming on the coils. Fill a squirt bottle with clean water and begin rinsing the coils, catching the overflow with the Shop-Vac. You may need to rinse the coils several times to remove all traces of the coil cleaner and dirt.
Take your Shop Vac and place the hose around the condensate line discharge outside by your condensing unit, and seal it around the pvc line with duct tape. Let the Shop-Vac run until all the debris is cleared out of the line. If you don't take this step, the crud from the coil will plug the drain and cause a back-up.
I don't like "in-place" coil cleanings. But I can also tell when someone is up against it. Be careful. Good luck and God bless you!

If you are referring to the indoor coil on a central A/C, I can assure you that you may not want to tackle a cleaning job. It can be a bear for us techs so I'd leave it to a pro. You can cause damage to vital parts which would only add to your problems. You didn't mentiion how you found out that it would be necessary to clean the coil?
