I use the chemical Guys drying towel to soak up most of the excess water then run over with a MF cloth to pick up the rest, works a treat and usually use the shammy on the windows.
Can anyone advise on how to wash the MF cloths and drying towel as mine are dirty and I tend to buy new ones rather than wash them lol.
To wash the microfibres put them in a load on their own - use a non-bio washing liquid or a dedicated microfibre detergent and don't put any fabric softner in. Wash them on a 60 degree wash and then tumble dry.
It's sometimes worth running the washing machine with an empty load first, just to remove any bits and pieces that may have built up in the detergent drawer.
Hope this helps
