1.- Wash all window
Use glass cleaner, or one squirt of dishwashing liquid in a spray bottle filled with water, and wipe down with a microfiber cloth. Pick a cloudy day so you can better see any streaks
2.-Vacuum dusty canvas, cotton, and treated fabric blinds
Use a low setting with a brush attachment. Vinyl shades can be wiped down with a dampened microfiber cloth if they need a little more attention
3.-Moderately dirty window treatments need a two-step approach
Start by dusting or vacuuming the valance and frame, then vacuum from top to bottom using the upholstery attachment for drapes, and the brush attachment for blinds. Or submerge blinds or shades in a few inches of cool water and two teaspoon of dishwashing liquid ( check labels first to make sure this is safe). Take out the metal weights first; they can rust.
4.-If your window covering are dirty, check labels for cleaning instructions
Some cotton, polyester, rayon, and wool drapes can be machine washed on delicate. Always send lace, linen, satin, and silk drapes and shades to professional cleaner
5.- Clean the walls
Dust, wash, rinse, and dry painted or wood-paneled walls
