It’s important to remember that velvet is not an actual fabric like cotton, or polyester, but is technically a weave. Because it’s a weave it can actually be made up from different fabrics, along with different amounts and percentages of those fibers.
It depends on the exact kind of velvet you are trying to clean, on the steps you will need to use to clean it the best, and safest way. Because velvet is somewhat delicate you would typically want to bring it to a professional dry cleaner as they have the proper equipment and expertise to clean them, but if you find yourself in a situation where you need to clean the velvet curtains yourself then there are ways to do it.
Because crushed velvet curtains are set originally with heat and water, if you use wet cleaning it might remove the crushed effect and appearance so be careful.
It’s usually better to use wet cleaning outside of that, or to use some wet and dry cleaning mixed together. Like I originally said, because velvet is not actually a fiber but is a weave, these stesp always vary accordingly.
Tufted velvet has latex on the back and if you dry cleaning or any home solvent cleaners it might ruin it.
The basic steps on cleaning your velvet curtains to use use a mixture of a small amount (around a 1/2 teasppon) of dishwasher detergent mixed with water. Mix it up very well and then only used the suds themselves to clean with. Do not pour the mixture directly on the velvet curtains. Use very small amounts and use discretion on where you apply it. Do not get the velvet curtains completely soaked as this might ruin them.
You should always clean the velvet curtains towards the flow of the nap. Do not brush against it as this may cause permenant damage.
After you have cleaned your velvet curtains to your liking you should let it sit at least 24-48 hours before you try to hang them back up, or put them back where they were originally being used.
The trick, as it is with many situations where you are cleaning a material that is difficult is to use common sense and not be impatient. It’s much better and easier to spend a little extra time preparing and cleaning correctly than it is to go out and buy new curtains.
