sill brush is like a brick dont make me laugh
best brush i ever used i got lazy since using sl though
just hoping gardiners gbring out a sill brush
first cleans i clean frames first rinse then drop brush down and clean
off any crap that may of attached itself tthen do the glass repeating
the same process on each window.
ive watched loads round by me scrubbing away at filthy windows and frames
without ever checking their brushes are retaing any the crap probaby
transfering to other windows as they go along then whinging about the
results.
