I'd like to repaint my 100-year-old wooden front porch. It almost certainly had lead paint at some point. I would very much like to avoid stripping it, or any other procedure that might mobilize the lead paint, as I have young kids (and, if any dust were created, it would be very hard to keep it out of the front yard).
However, the porch also has lots of dirt ground in to it, and in some places the paint is totally worn away. Is there a way to properly clean the wood without mobilizing the lead paint?
