Another way to quickly clean a window is to use a special device, such as a robotic glass cleaner. It is enough to plug it into the network and install it on the window, and after finishing the work, rinse the rag and put the device away for storage.

Difficulties with bars

If the window frames open into the living space, then cleaning windows with bars will not be difficult. The situation is more complicated with cast non-removable structures.

There are several options:


  1. Use a steam cleaner.
    Its nozzle is inserted into the existing opening and the device is connected to the network. Under the influence of steam, all dirt will dissolve, even without the use of detergents. However, if the opening is too narrow, then wiping the glass with a rag will not work.

  2. Residents of the first floors (provided the windows are low) can use the Karcher mini-wash.
    This device supplies water under high pressure. After using it, not only the glass, but also the grilles will be perfectly clean. If Karcher is not available, then a regular hose will do, but its efficiency is lower.
  3. Call specialists. They have devices that can help you cope with any task. However, cleaning services will cost money.

The last and most labor-intensive option is removing window structures. Although it will not be possible to do without special knowledge and tools.

Window cleaning steps

Before general cleaning, you need to remove all items from the window sills, remove or move roller blinds, curtains, and blinds. Prepare your equipment: if there are no special equipment, you will need a rag, detergent, gloves and a basin.

Sequencing:

  1. Start with the frame and window opening. These are the most contaminated areas; if you wash them last, you will splash the glass and will have to wash them.
  2. Wash the outside of the windows first - they are dirtier than the inside.
  3. Remove dirt with a damp sponge or rag, then apply detergent to the glass, rinse with a clean cloth, moving from top to bottom, and wipe the window dry.
  4. Wash the inner glass in the same way, but wipe it from left to right. This way you will immediately notice whether there are any streaks left on the outside of the window.

Assistant devices

To make the process of washing windows easier, you can use special devices, of which there are many today. They not only save time, but also help you get to hard-to-reach places if you can’t reach them.

Such devices are indispensable for residents of high-rise buildings, as well as for owners of glazed balconies and loggias:

  1. Telescopic mop . It has a retractable handle that allows you to reach corners at great heights.
  2. Magnetic brush . The device is represented by 2 halves, which are attracted to each other by magnets. A person washes only the inside, and the brush located opposite him repeats his movements on the outside of the window.
  3. Rubber scraper with a short handle (water scraper). With its help, it is easy to remove foam and dirty water from glass after basic cleaning.

Chalk.

When using this cleaning method, it is important to maintain proportions. If you add a lot of chalk, it will leave white marks on the windows. What do we have to do:

  2. Soak a napkin in the solution, squeeze out excess moisture and wash the glass.
  3. Wait until the surface is dry and remove any traces of chalk with a clean, dry cloth.

Salt and soda.

Salt will protect the glass from icing, and soda will help remove complex stains. Prepare the cleaner:

  1. Add 1 tsp to a glass of water. soda, 2 tsp. salt and 1 tbsp. l. vinegar.
  2. Stir well to dissolve the salt and soda crystals in the water, otherwise they may leave small scratches.
  3. Wash the windows with the solution.

Melamine sponge.

Melamine works like an eraser - it erases any dirt, so it can be used to remove grease on kitchen windows or other stubborn stains and deposits. The sponge should be moistened in water without adding soap.

Newspapers.

They are not used to wash glass, but to remove excess liquid. Paper absorbs moisture and detergent residue well, so this method helps get rid of stains. But newspaper can leave particles of paper or traces of ink on the glass, so it is better to choose thick craft packaging without inscriptions.

Household chemicals

On sale there are budget formulations based on ammonia and environmentally friendly products with hypoallergenic components. Popular budget sprays:

  • CIF;
  • Help;
  • Clin.

The TOP environmentally friendly hypoallergenic compositions include:

Products marked “eco” are more expensive. But they are made from less aggressive components and without a pungent odor.

Do not use dish soap, shampoos or washing powders to clean windows. They foam a lot: it will be very difficult to wash off such an amount of soap from the glass. Avoid compositions with abrasive particles to avoid leaving scratches on the glass.
