It even left a residue on concrete. It took quite a bit of cleaning. If I switch to Timbor, this residue will not show up. Is this correct?
Timbor leaves a white powder on the surface and is more difficult to paint or stain over. BoraCare tends to only leave a residue if not mixed well with warm/hot water.
