Summarize the following:
Take the large bowl or container that you initially soaked your feet in and fill it with cold water. To speed the drying process, slowly dip your feet in the ice cold water after the polish has hardened a bit. Keep them there for several minutes, or as long as you can bear. Doing this will also set the polish and make it more durable. Dip a concealer brush in acetone or nail polish remover. Tap the brush on some paper towel to remove any excess acetone. Use the brush to carefully clean up any edges or polish that got onto the skin. The concealer brush will allow you to effectively clean any edges without messing up the rest of your pedicure. Use your favorite top coat or a quick-drying top coat to cover the nails in one layer. This will finish off the look for your French-pedicured nails. You can also try a top coat that is slightly pink to go for a softer look. Let the top coat dry completely before putting your shoes on! A quick-dry nail spray will help your nail polish dry even faster and allow you to be on your way without worrying about smudging your pedicure. These quick-drying sprays have high levels of solvents that evaporate quickly. Hold the can a few inches away from the surface of the nails and spray over the nails quickly, without getting too much of the product on the nails. You can also use a quick-drying topcoat to ensure that your nails dry quickly, usually within a few minutes. Great brands to try are Sally Hansen and OPI.

Summary:
Let the white nail polish dry. Clean up the polish. Coat your nails with clear polish. Spray the nails with a drying spray. Finished.
