So, our washer and dryer were on their last leg. Due to a killer Black Friday sale, we purchased new, top-loading HE machines. I had done quite a bit of research, even on detergent. I was led to believe that you CAN use regular detergent, as long as you use much, much less so that you don't have sudsing. Me being a frugual as I am (okay, so maybe I've advanced to just "cheap"), I refused to buy new HE detergent. I'm currently washing my 3rd load, using 4 tablespoons of powder detergent. It has a glass top, so you can watch it washing your clothes (our whole family watched the first load wash for 20 straight minutes!!!), there is ZERO suds and our clothes have never been cleaner, softer, and smelled so great. I had chalked the whole HE detergent up to money-maker for the detergent companies. They are slightly more expensive, and from what I can tell, probably just contain a lot more water than regular detergent. However, I'm now finding things online about how if something happens to your washer, that your warrantee won't cover it if you did not use HE detergent (I'm unaware of my policy, haven't read that much into it yet). How would they know? What does it do? Basically, am I screwing myself by being cheap with my detergent? Am I going to "ruin" my machine? Do those who have HE washers use HE detergent? I do occassionally make my own borax/washing soda/fels naptha detergent (but only when money is really tight b/c I prefer the commercial stuff), anyone use that in an HE? Thanks in advance!
