I used Griots "Leather Care" liquid today. I realy liked it.

But can someone clarify how I am suppose to use it.
The video on the website says leave for 30 mins ( maybe 30-60 mins? ) come back and wipe of any excess.
The bottle just says apply and wipe off.
Another video I saw said apply and wait 5 mins.

Is there anything wrong with leaving it 30 mins or longer?
Does it need to be wiped down after? Lets say I apply and in 30 mins it`s all been soaked up and there is nothing visible to wipe off.
Let`s assume the leather has just been cleaned and in good condition.

And can a microfiber towel, cloth applicator be used when applying?
The video shows the guy using one of the yellow spongy pads.
