White vinegar

The white vinegar

White vinegar is particularly effective when it comes to cleaning and housekeeping, especially thanks to its degreasing power. The windows are no exception to the rule. To be sure to remove the most important dirt, proceed as follows: – Prepare a mixture consisting of 3/4 liter of hot water, and 1/4 liter of white vinegar; – Take a cloth, soak it with the resulting mixture and pass it over the surface of the glass. No need to force, the effectiveness of vinegar should allow you to clean your windows without much effort.

Soap and rubbing alcohol

If you have tried several techniques but some tasks refuse to leave, it is probably time to think about this mixture.

Apply the mixture to the surface to be cleaned and leave for about ten minutes, before rinsing with clean water. Voila, you’re done!

A mixture as ecological as it is natural appears to be the most efficient: the white vinegar-baking soda combination will indeed surprise you! Soak a sponge in white vinegar and pass it over the glass of your fireplace, on which you will have previously poured a layer of bicarbonate. After rinsing with clean water, your glass becomes like new again!

Cleaning the window

Here too, it is a painstaking, time-consuming and tiring job. MERCI+ housekeepers can save you a lot of torment by taking care of your windows, quickly and efficiently. Their expertise is also valuable, because depending on the material with which the window was made, the cleaning technique varies significantly.

The wooden window

If your window or window sill is made of wood, you should especially not use ammonia. Apart from being uneconomical, it could lead to irreversible damage. Using hot water with a little dishwashing liquid is a technique that is as simple as it is effective. Once the cleaning has been carried out, it is relevant to extend the life of the wood by applying varnish or paint if the wood is painted.

The aluminum window

Aluminum is a material that tends to damage easily. Several precautions should be taken if your windows are made of aluminum. First of all, it is advisable to avoid all chemicals. Wash your aluminum windows with warm water and a mild detergent, before applying a soft cloth to wipe them.

The pvc window

To avoid irreparable scratches on your PVC windows, you must use a soft product. Water combined with a glass cleaner is an effective combination. Above all, give preference to a delicate sponge (especially not the green part, which is abrasive) and leave out sharp objects.
