Community Reviews

Kirkland Signature Ultra Clean HE Liquid Laundry Detergent is a concentrated, premium-feeling detergent that cleans well and is often compared with Persil and Tide. The enzyme blend gets credit for handling tough stains, including mechanic clothes, and it is also noted for having little to no pungent fragrance. The sale price is described as especially strong, with the deal recurring about every three months and a purchase limit of two. The main caution is that the formula and production are reportedly changing, so stocking up has been a common reaction, and it may foam more than Tide in HE machines if too much is used.

Common Questions (5)

  • It is described as premium-level and comparable to Persil and Tide, with similar stain-fighting enzymes such as protease, amylase, and mannanase. Consumer Reports is cited as placing it just below Tide, and it is also reported to clean mechanic clothes well.

  • It reportedly goes on sale about every 3 months, and this sale price is described as the usual sale price. The regular price is said to have stayed unchanged for about a year.

  • The purchase limit is 2, and it is also stated that you can buy 2 each time you go. That makes it practical to stock up while the sale is active.

  • It can produce more foam than Tide in an HE machine, but less than Persil. Because it is concentrated, using less detergent may reduce excess suds.

    RelaxedCreature628mickey1987

  • A production change is reportedly coming as Henkel exits the North American retailer-brand business and production shifts to First Quality Enterprises. If you like the current formula, buying extra now is suggested because the next version may be different.

It's actually very comparable to Persil considering it has protease (protein stains like blood, eggs and other body fluids), amylase (starches like sauces) and mannanase (sticky stains like lotions) enzymes just like persil. If you add biz powder you also get lipase that will get your clothes as clean as they can get.

This deal is easily a no brainer.

Yea the Costco Kirkland detergent is a premium level in the same as persil and the good tide. Just much cheaper.

I use this on my mechanic clothes. Works great.

actually, per oz, it has been beaten like 6 times in the last year by amazon s&s sales on arm and hammer+ detergent, and recently was beat per oz with tide ultra oxi boost. however, its still a solid deal for detergent and is usually the best priced when on sale in costco

It goes on sale every 3 months or so. The regular price hasn't changed for about a year but the company that makes it is going to stop making it for Costco. So if you like it then you should pick up a couple at time.

There isn't any information who will be making it for Costco after the change
