Cleaning mini blinds can seem like a daunting task, but with the help of a household cleaning product and some water, it won't take too long to get them looking as good as new. Mini blinds collect dust, dirt and grease, so remember that putting the job off will only increase the workload. You should try to clean your mini blinds at least once a year or more often if your blinds are situated in an area where they are exposed to higher levels of dirt and grease, such as the kitchen.
Close the blinds and make sure all the slats are facing the same way. Using the hose on your vacuum cleaner, vacuum off any excess dirt and dust particles from the slats. Once this is done, close the blinds the other way so that you can clean the reverse side.
If you have some outside space and the weather is dry, it would be better to clean the blinds outside so that you don't have to worry about making a mess. If you can't do it outside, lay the blinds in the bathtub to avoid making a mess. Either way, you need to protect your hands with rubber gloves before handling the ammonia. If you are cleaning the blinds outside, lay the blinds out on the ground on an old towel or sheet. Mix one-part ammonia to one part of water in a bucket. Wipe this solution over the blinds with a sponge on both sides of the blinds. Leave the solution to work for about five minutes then hose down each side of the blinds with water.
If cleaning indoors, fill the bath with enough ammonia-water solution to cover the mini-blinds by an inch or two. Open the blinds a little so that you can clean in between the slats and fully extend the blinds so that the dirt can be removed from every single slat. Place them in the bathtub and use a sponge to wipe them down with the ammonia-water solution. Wait for five minutes before rinsing the solution off of the blinds with a hose, or by filling the bath up with clean water.
Dry the blinds off with paper towels or a soft cloth, remembering to dry between each slat. Either hang them to dry outside on the clothesline or over the shower rail in your bathroom. Leaving the blinds open will speed up the drying process. Another option would be to lay them on a clean, dry towel, turning them over when the first side has dried.
To keep them cleaner for longer, try wiping your mini blinds with an anti-static dryer sheet. This will reduce the amount of dust that builds up on your blinds. Weekly vacuuming or wiping with normal household spray cleaners will also mean you won't have to do a big ammonia water wash very often.
