Well, there is one thing about Tide detergent, that makes me dislike them right off the bat. Tide is produced by Proctor & Gamble, which still uses animal testing. That's not something I endorse.
I've used Tide twice at my laundromat. The first time I ended up with a lot of streaky undissolved powder at the end of my wash cycle.
At the time I chalked it up to a faulty machine, but I have since heard other people mention the same problem.
The second time I used it my clothes were (mostly) clean. I would have liked to have washed them again but I didn't have the quarters, and was forced to were them. In addition to only being MOSTLY clean, they were stiff and uncomfortable.
I thought maybe I had used too much, but when I re-read the instructions, I found that I had followed them to the letter.
Lastly, and this could just be nitpicking due to my other problems with Tide detergent, I think it smells horrible. If I'm going to spend that much money on laundry detergent I want it to a.) clean clothes, b.) clean clothes, and c.) smell good. I also want d.) to use a product that didn't make some poor capuchin monkey's miserable little life even more miserable.
Tide fails. Completely. 0 out of 5 from me.
