I bought some propylene glycol, wet oasis foam, distilled water and a cooler. How big a piece of foam should I use in a 30 liter cooler? How much solution should I make for this piece?
Also, can someone tell me what exactly the PG does in the solution I'm supposed to moisten the foam with? Is it safe to handle?
