Will this stain or darken lighter-colored clothes?

No, it should not. It simply helps to keep your darks from fading with washes. Great product.

Does it help darken blue jeans? What if they are two-toned faded on purpose?

I does not darken the colors it just keeps them from fading as quickly as when you use regular detergent.

Can this be used on HE washers?

There are instructions for HE washers on the back of the bottle

Will it discolor white lettering on dark clothes?

I've used Perwoll for several years, and never had any discoloration. I think the product is great.

Magic Potion, I am telling ya!

There is some serious German witchery going on. My faded dark silk and cotton outfits are restored to their former glory. How is it even possible and how it works, I know not, but this chemical concoction works miracles. I wish there was something as effective for eradication wrinkles and greying hair. Until such time these things are invented, I’ll have to be content with this magical detergent for now.

Great Product

Great product! Keeps my dark clothes dark, and helps with pilling. Also, it makes my clothes soft with a nice scent.

Blir inte så bra mörk toning men bra tvättresultat.

Gör bra tvättarbete, hade hoppas på mer "toning" av mörka plagg.
