Record cleaning

So I finally had the opportunity to fetch my system from my parents garage(1000 miles is a ways to lug a system as big as mine)  now, I want to clean the records. From what I've read, isoproponal? Is the alcohol to use for vinyl as it won't attack the plasticizers, by l but I also have a large inherited connection of 78's that won't be played because I don't have a player for them,  and I'm assuming they need different care. 

Now, I would prefer to use something that I either 1) already have, eg.  Simple green, 409, etc,  or 2) something that is available locally easily(which is hard, living in a town of 10,000, and 2 hours away from an established city) 

My system isn't very high quality,  it's a system from Sears from the 80's,  but I'm hoping that cleaning the vinyl will help increase the audio quality
