No. You can clean some exterior-facing glass from indoors when that specific window is designed to open or tilt inward, but there is no safe method that works for every window. If you cannot reach the glass without leaning out, climbing onto the sill or relying on a screen, stop and arrange suitable access or professional help.
Which windows can be cleaned from inside?
Tilt-in double-hung windows
Some double-hung windows are designed to tilt into the room, bringing the exterior-facing side of the sash within reach. Andersen documents this feature on its 100 Series double-hung windows. Use the operating instructions for your exact model; one manufacturer’s latch sequence should not be assumed to apply to another.
Support a tilted sash as its manufacturer directs. Andersen says to hold it or rest it on a table or chair while cleaning. See Andersen’s instructions for 100 Series double-hung windows.
Other opening windows
Sliders, casements and other opening designs provide different kinds of access, and their hardware and cleaning instructions vary. Do not force a sash or assume that opening a window makes its outer glass safe to reach. OKNA’s care guide gives separate operating instructions for its double-hung, slider and casement products; check the guide for your own manufacturer and model.

Fixed or unreachable windows
If the exterior glass remains out of reach from a stable position indoors, the reviewed guidance does not establish a universal consumer tool or method that is safe for every height, glass type, coating and site. Stop rather than improvise a longer reach. Difficult-to-access windows may require specialist equipment or a competent window-cleaning service.
How to clean an inward-tilting sash safely
- Identify the window. Find its manufacturer and model if possible, then read the operating and care instructions before moving the sash.
- Stay on a stable interior surface. Do not climb onto the sill or lean outside. A screen is not fall protection: OKNA explicitly warns not to lean out to clean exterior glass and says screens will not prevent a fall. Read its November 2023 operating and maintenance guide.
- Open and support the sash as directed. Tilt it only if the model is designed for that operation, and keep it supported while you work.
- Use compatible, nonabrasive materials. OKNA’s guide allows a soft cloth and a mild household cleaner such as dishwashing detergent, followed by wiping and rinsing with water. It warns against harsh chemicals, abrasives, high-pressure sprays and razors. These are OKNA’s instructions, not a substitute for the care directions for another maker’s glass or coatings.
- Stop if access is uncertain. Do not lean farther, stretch past a safe position or improvise equipment to reach a pane that the window’s design does not bring within reach.
When should you arrange suitable access or professional help?
The UK’s Health and Safety Executive (HSE) advises avoiding work at height where reasonably practicable, including by cleaning windows from inside. Where work at height cannot be avoided, its workplace guidance calls for planning, equipment suited to the height and site, and competent workers. It notes that difficult-to-reach windows may require specialist access equipment. This is UK workplace guidance, not a household risk assessment or a universal homeowner rule. See the HSE guidance on window cleaning at height.

In the United States, OSHA’s window-cleaner positioning provisions set conditions for employers and trained workers using occupational fall-protection systems, including requirements for anchors and attachments. They do not make a household window a safe anchor point or provide a DIY setup. OSHA’s 29 CFR 1910.140 personal fall-protection requirements address workplace systems. A separate OSHA interpretation letter dated May 21, 1982 is historical context, not a current standalone homeowner method: Clarification on window-cleaning operations.
