I do not use anything other than microfibre cloth, including wash mitts, drying, application and buffing towels. I used to use Autopia in the USA, but with the exchange rate as it is these people in the UK are just as good and market most of the same stuff as Autopia UK site is http://www.cleanyourcar.co.uk/microfibre-cloths/cat_5.html
I used to put the microfibre cloths in the washing machine when I need to clean them, but I find I get better results hand washing in a bucket with Sonus Der Wunder Wasche which is also good for bringing foam polishing pads back like new. Have a look at the detailing guides for alternative polishes and waxes to the Autoglym.
tango.try the washing machine again and use white vinegar in the rinse compartment,you will be happy.very cheap white vinegar at asda.
