Does using powder automatically mean you are at risk for pipes clogging up? I also have somewhat hard water. I always make sure the powder is dissolved (I swish it around in the washer) before I put my clothes in.With my somewhat hard water, it pays to use a liquid: zero chance of clogging
Before I used Foca (powdered), I used the Aldi brand liquid detergent and it is quite good and reasonably priced. I would still buy it but Foca is just so cheap. Foca also has a liquid that I think works in HE washers but I have not tried the liquid.
