STTP Powder 2.5lb

Yay, my laundry finally looks clean and bright! It does not irritate my sensitive skin, but I do a second rinse on all my laundry.

I’ve been using the Pure Original Ingredients Sodium Tripolyphosphate in my laundry, and it’s truly brought back that 1970s-level clean to my clothes! Adding this powerful cleaning agent to my detergent has noticeably improved the freshness and cleanliness of my laundry. My clothes feel cleaner, brighter, and have that fresh, crisp feel that I remember from the past. One thing to note, though, is that the instructions aren’t super clear, so it’s a bit of a trial and error process to figure out the right amount to use for your laundry load. But once I found the right balance, the results were definitely worth it. It works great as a water softener too, which helps with detergent effectiveness. I’ve noticed that the combination of this with my regular detergent really gets rid of stubborn stains and gives my laundry that deep, thorough clean. The 2.5 lb size is a good value, and you don’t need to use a lot, so it’ll last for a while. Overall, I highly recommend this if you're looking to improve your laundry game and get that deep clean we used to get in the past.

Works like calgon. Just make sure to follow directions for mixture to avoid film

Very nice packaging. Easy open and reseals well. Product good quality.

Appears to work as desired for laundry.

World great to help laundry get clean. I use this in every load.

We have well water and a whole house water softner system. Our water however has a high amount of total dissolved solids, iron specifically! This product has been a game changer! Clothes seem to be rinsing better and getting cleaner in the wash, I add 2 tablespoons to almost every load and have been able to use less detergent this way as well. Ive turned on subscribe and save for this one it's a must have for anyone with hard water and a heavy laundry load!

I’ve been using this exact product for the past 2+ years. I just opened the package I received last week and it smells like sewage. It’s never had even the slightest odor before. I’m not putting this in my laundry. I’m returning to Amazon (even if opened) and ordering a new package. Hopefully that one won’t stink. UPDATE-replacement smelled as bad as the original. I wouldn’t order this for the time being. I’ll look for another source of this product. I can’t believe the seller would ship this stuff…worse still, the new Amazon app doesn’t allow contact with seller, so they probably have no idea this is happening.

Excellent for making food
