After we had the "hot" Persil, I was wondering if it was a manufacturing defect, like someone had put in too much scent. When I said it stunk the house up, it really made every last room in the entire house smell like it.
After 6 months in the garage, it smelled like normal Persil again. I think thie was back around 2011 or so when it happened. Unfortunately, due to allergic skin we can't use Persil anymore. We're stuck with All Free and Clear.
And we have noticed that with All Free & Clear the liquid version washes out of the laundry in the rinse cycle faster than the powder version does. It's usually the other way around.
