i bought the lot from b&q,the pipe is approx 18mm by 12,i only use one pipe for cleaning and rinsing but i do change the felt end regularly,all i use are moth ones cut to size.
i dont get a damp band as i always finish in the run off of the records

i basically adapt what this guy uses,it also has some good advice too . http://cleaningvinyllps.blogspot.co....right-way.html
