It sounds like white powdery mildew, which happens sometimes when the plant isn't getting much sunlight and/or the leaves have been watered and it is in sitting an area where the plant doesn't get much air circulation .
You can mix 2 tablespoons of dawn dishwashing liquid with 1 gallon of water.
Then pour into a spray bottle.
Take your plant outside and spray it really well with the solution. Gently wipe the plant with a cloth, making sure to get all the powdery mildew off.
Once you have done this, then use your garden hose to gently rinse the remainder of the mildew residue off the plant.
Let it sit outside in the SHADE until the leaves dry sufficiently, before you bring it back inside.
Remember to water your houseplant from the bottom to avoid mildew growth in the future.
Hope this helps.
