I agree with the guys comments so far.
It is doubtful that you have a real suede, normally these are 5K upwards to buy. Looking at the back of the fabric you should see a nice leather finish instead of a glued backing of poly or nylon.
Ive cleaned quite a few real suede's, its not for the faint hearted or unsure. Lint free cloths are used with a foam cleaner, dried then a reviving sponge is used. This is the same as cleaning Nubuck, full testing is required to make sure no colour is lost, or darkening occurs as nubuck and suede both absorb liquid.
If in doubt leave it to a Professional.
