Would like to remove lint from a micro-suede washable jacket.

Find yourself a good old-fashioned clothes brush, usually used for gentleman’s clothing. Maybe FullerBrush people, but Google it.

Due to its texture the micro-sued is going to pick up lint. I would wash it separately in cold water and then add a little Downy or vinegar to the rinse.

Try a swearer shaver or “sweater stone”.

Try wiping it down with a damp washcloth. I have eight cats, and the EASIEST, and MOST EFFECTIVE way to get cat hair off of ANYTHING is simply wiping it up with a damp cloth. I've even used a damp paper towel. I would think it may work with lint or other things sticking to microsuede. The hair just collects onto the cloth in nice bunches, which you toss, and keep on going to get all the hair off. A woman who used to clean my house gave me this tidbit of knowledge years ago. It hasn't failed yet!

Wash it with woolite by itself or other suede garments

Try slipping on a rubber glove and wiping it off. Works great for removing cat hair from my furniture, clothes, etc.
