Clean window blinds, the kind that are on sliding glass doors. They feel like they are fabric
Here are a couple sites to help you out.
I have fabric vertical blinds in one of my rooms. I vacuum them and when needed and periodically use a bucket of 50/50 water and vinegar and use a microfiber cloth and blot the fabric to keep it fresh.
I found these, hope they help:
I would vacuum them first. If they are soiled, remove them and lay them flat. Try an upholstery cleaner in an inconspicuous spot first, then clean the entire blind.
The easiest way to do this is with a vacuum cleaner brush attachment. Alternatively, if you do not have one available, a microfiber cloth will work perfectly well. Whichever method you use, wipe down your fabric blinds. Then, soak your sponge in soap and water.
