What I use, can't go wrong with Sonus, German.

Blade is great at drying, but towel is less risk, more wise choice.
You'd still have to towel dry with a blade, to get best possible finish, which ideally you'd use last touch or similar.
Blading first would leave car too dry to work the towel easily.
I did use a blade for a long time, but towel takes very little time, so no need for the risk.

Diluted makes 8 litres, so good for the money.
So many uses, claying, polishing and waxing to help removal, and to finish off to collect any residue dust.
When machine polishing to prime the pads.
Quick wipe of wheels to help shine a little.
When wet sanding.
