Hi Guys, just to clarify you can use little waffle cloths with either the Vikan,Dragonfly,or Unger systems, for cleaning internals by hand you just use one damp with water to clean the glass then use a second one dry to polish off for a smear free finish, if you are cleaning internals at height just use a standard telescopic mop which will extend from 100cm to 180cm, or a ( 2x1mtr ext pole,2x2mtr ext pole, 3x2mtr ext pole, or 5x2mtr ext pole.) if you are using an ext pole just take off the plastic end piece and stick on an aluminum flat mop frame the ones which have two velcro strips which will grip the little waffle glass cloths and allow you to clean at your required height. If anyone is interested in pricing just send me an email and i will send on more information. Regards Tadgh
