These methods release a great deal of lead dust. Use chemical strippers. They may also be toxic, so wear skin, eye, and lung protection. Instead of repainting, you may also cover lead paint with wallpaper or sheetrock. Use only cold water for drinking and cooking.
Hot water is more likely to contain lead.
The longer water sits in pipes, the more lead it accumulates. Let your water run for one full minute each morning before using it. Typical carbon-based home water filters do not remove lead. Antique, hand-crafted, terra cotta, and highly decorated china usually have the highest lead levels, but any china can have lead glaze. Glass dishes are best.
