I use Kwik Off primarily for removing stubborn polishes that require a bit of soaking - such as glitters and textured polishes. Being able to soak my fingers in this hydrating remover is so much easier than trying to remove stubborn polishes the traditional way. There's no scrubbing required and it doesn't leave my nails feeling dry and damaged. Kwik Off really gets the job done. I especially love that it's affordable and no-nonsense. This is one of my all time favorite removers. You cannot beat it in terms of performance and ease of use. I find that it's time to replace the tub when the sponge inside is starting to show stains or when the remover is notably discolored. I usually get about a month of use out of each container but I paint my nails about three times a week so I use mine quite frequently. In a pinch, you can also freshen this up by adding a bit of a polish remover of your choice. I find that can extend the life of my Qwik Off.
