I know squeaks prefers the tiny unger microfibre, but most will get on better with the large ones.
Cleantech do their own branded ones, same as the large Unger ones but a little cheaper.
These make life so much easier...really, they are the bee's knees.
flat weave microfibre though, the dirt cheap ones are not a patch on the proper ones.
Get them from a proper supplier, B&Q only do the cheap stuff, as do Wilko's etc.
