If so, was it neat or could you get it to work when diluted - and at
what dilution?

If you are going to use chemicals to do it you might at least use the
right ones. Anything else will be almost a waste of time. Likewise if
the conditions are right for moss and lichens they will quickly return.

"Wet and forget" is about the simplest to use.

Don't expect miracles. The moss is there because of the cool and damp.
It will return next winter without fail.
