When you're using Fluorouracil, you should make sure that the skin & the area around it is absolutely dry before applying it. Even if it's only damp, there's something about Fluorouracil that makes it more caustic in the presence of water. This probably applies to sweat too. Make sure you apply the F to absolutely dry skin an hour before you go to work. By then, the F should have been absorbed by the skin and you can wipe it off. Or wash it off. Under normal circumstances, your skin at the pre-cancer site will start to ulcerate after about a week and will continue to get worse till you can't stand it any more. If the technique above doesn't work in the first week (i.e. if your skin gets very raw & painful in the first week), then you may want to opt for liquid nitrogen, but that will leave a white spot.
