Done a first clean on a house with old leaded windows (one with small individual panes) with wfp but a some were leaking into the inside from lead and tops of frames. Now can clean some of this house with wfp but most has to be done by hand. First time doing these kind of leaded windows would like to know what would be best/fastest was, was thinking big microfiber cloth as squeegee could take ages?? What you think?
