I've been using Era liquid detergent for the last 15 years in my top-loading Maytag A606. We like Era for two reasons: its cleaning ability and its lack of heavy perfume. The last couple of bottles I've bought seem thin, and I seem to have to add more to make a few suds. Has anyone else noticed this? I suppose I could go back to Tide, but I like my clean laundry to smell like clean laundry and nothing else.
