Thomann Microphone Cleaner

I bought this as I became conscious of different people using my mic at gigs and realised that not only should I not allow members of the public breath and spit all over my mic , but I should really buy a product to keep it clean.
I bought this cleaner as it seems reasonably priced and handy.
If I'm honest, I’m a little disappointed.. mainly because it arrived with ZERO instructions on how to use it. I know its not exactly rocket science but I have no idea whether i just spray it on and leave it, or whether i spray and wipe off? Etc etc..
Not the end of the world but is just strange and kinda feels like a waste of money.

Pros.. if you are already familiar with how to use these cleaners, it is probably great and value for money, but if not... see cons.

Cons.. came without ANY instructions or directions for use.
