Stain Removal Tests: UK Ariel (P&G) and Persil (Unilever)

Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

Help Support :

Another benefit of Unilever Persil: It rinses out well---even a little better than SA8, which is its closest competitor in that department (in very soft water).

As in past tests: Frigidaire front-loader; 18-minute wash using Whites cycle and 140-degree water.
 
WOO HOO!

Great news! Just what I have said all along, good to see nice unbiased testing, Persil is truely the best at cleaning and rinseing although lately I have been using Ariel on odd occasions this just proves why Persil is no.1 in the UK.
 
Eugene - what I'm interested to know is how did the UK formulation relate to the Henkel formulation?

You've got similar results to what I've found, and I've found Persil bio for me seems to have the edge on the biological detergents. Though the reverse is true for colour care products - Ariel colour has always performed better than Persil colour for me.

Perhaps on your next order you could test these? :-).

Also - don't suppose you could give a quick update so far as to a "league table" of detergents?

Must be something in the water :-) I have always found Ariel superior for stain removal consistantly for almost 30 years. Interesting test though!
 
When I say edge, I mean a very fine edge. The latest formula of Ariel doesn't seem to remove blood that well for my liking, which the previous formulation (with the old logo) never had trouble with. There really isn't that much of a difference between them, otherwise.

Thanks for checking this out, UK contingent!

A couple of things to remember:

1) These tests are conducted using a traditional American non water-heating frontloader. Your bio detergents may be formulated for profile washes, which allow a detergent to remove certain stains in warm water, then heating to a high temp to remove stains that respond better to very hot water.

2) Most UK washers have a much longer cycle than my machine. Total cycle time for me is 55 minutes (including an 11-minute final spin). Seems to me most of your machines have longer wash cycles (18-minutes is the longest wash on the Frigidaire).

3) I have mechanically-softened water. It is slippery even without adding detergent.

4) This is a very difficult test. I stained the towels heavily, then hung them to dry overnight.

I think both detergents are top-shelf; In my test, Persil took the checkered flag. Its rinsing ability is impressive, too.

My mother also swears by Ariel powder, though she and my father use Daz because they detest the current perfume. My sister switched back to Ariel because it cleaned better than Daz. I use Ariel tablets and think they now clean okay (they didn't when they came out at first).

I'm tempted to try Persil, but "WHICH?" says Ariel has the edge - just! Closely followed by Persil.

I think "Which?" said Ariel had better whitening capabilities.
 
Ariel

Hi Folks,
I have always found Ariel to be superior at stain removal. My elderly grandmother lives at home with us, she suffers from Alzheimer's disease as a result she has lost control of her bowels. We use adult nappies (Diapers) on her but leakage often occurs resulting in very heavily soiled bed linens. I find Persil not only leaves stains but also odours, Ariel removes the stains and odours totally. If there are any members that work in nursing homes or a Hospital laundry facility I'm sure they will confirm what I'm saying regrading the challenge of such heavily soiled items, in particular the removal of odours.

I'm an appliance engineer and my work clothes often get stained with grease; Ariel always outperforms Persil on my work clothes.

I am not biased toward any product and I do like Persil and always have Persil in the house but in my own experience Ariel outperforms it every time and has done for as long as I have been doing laundry 26+ years.

My friend is a manager in our local Asda, he says that Ariel is always the number one seller in his store. I will give him a call and ask if he can get detergent sales figures for the whole of the UK.

None of the stains in my test are pure grease, although there is fat in the barbecue sauce and the chocolate sauce; Ariel may, indeed, work better on petroleum-based grease stains. The stains in my test are the ones I've found difficult to remove from loads of kitchen towels, etc.

They both appear to be excellent detergents, to the degree that some have found Persil has the edge, others Ariel.
 
Unilever Persil has an extra enzyme that Ariel doesn't have - Lipase.
It should cut through greasy stains better than Ariel.

Personally, I find Persil absolutely excellent.
I can't stand the smell of Ariel, the pine scent is just overpowering.
 
Sales figures for 2006

Persil total sales in excess of £75million Ariel £50 million Sales of Comfort FS even outsold Ariel coming in at £60 million. Daz was £35million IIRC When sales figures were produced in March this year.
 
Enzymes

But Ariel supposedly has multiple glycosidases, and one of them could perform the function of lipase.

For what it's worth, I never found the lipase formulations (Ariel 'Future') to be particularly effective at removing butter/cooking oil stains in one wash, at 40 degrees C.

Remember the Lever 'Radion' advert, where woman tipped a basket of fried chips onto her neckscarf? Twaddle!
 
Sales figures,

I have the actual unit figures right for each one but I just had a thought. Cant remember if they were Million or Billion for each one. Rob
