I used to avoid painting my nails because I wouldn't be able to remove it when it was time to change the color. I tried tons of different nail polish removers and none of them would remove the polish in a timely manner. I tried this pure acetone and I was amazed at how well it worked. It removes almost any nail polish with one try. All I have to do it put some of it on a cotton ball or on a piece of toilet paper and rub for one second or two and it's gone. The acetone also works very well on acrylic or false nails. It dissolves the acrylic after you soak your nails in it for several minutes. That beats trying to pry them off with your natural nail peeling with them! It also dissolves the glue so that the nails come off with ease. The only thing I don't like about using acetone is that it leaves my hands and nails very dry. My nails feel a little brittle after I use it but I put cuticle oil on my nails and it brings them back to life.
