The test I apply here is, "Can I independently verify from personal 
knowledge ALL the tagging and location info" before using odbl=clean. 
For footpaths, that may mean removing designation tags if you can't 
remember whether it is footpath or a bridle way. Look out also for any 
un-relicensable mapping notes. I also remove all tainted nodes, if 
necessary replacing them with new ones aligned to Bing imagery. The most 
difficult is paths going through woods or forest. You may well have to 
end up just putting node at either side and hoping that the unnatural 
straight line is enough to attract the attention of the next mapper 
walking in the area.
