Cleaning professionals will never tell you the most important thing: their “signature” floor cleaning products are a myth.
The perfect shine of parquet or tiles is achieved not with a gel for 1000 rubles, but with... ordinary black tea leaves.
Yes, the same one that was left after evening tea.

Black tea infusion contains tannins, which create an invisible film on the floor surface. It repels dust and masks small scratches.
Just pour 3-4 tea bags with a liter of boiling water, let it cool, then wipe the floor with a cloth soaked in the infusion. No streaks, only a mirror shine.
For laminate, add 1 tbsp of vegetable oil to the solution - it will “seal” the joints.
If the floor is very dirty, add 2-3 drops of lemon or eucalyptus essential oil to the infusion. They will enhance the antibacterial effect and leave a light aroma. The main thing is not to overdo it with the concentration, otherwise the oil will make the surface slippery.
And remember: the tea method is not suitable for light-colored parquet - yellowish marks may remain.
For such cases, replace black tea with chamomile tea: it is softer and does not stain the wood.
Tea leaves are not the only “secret” ingredient.
For example, for stone floors, use water with white vinegar added (1 cup per 5 liters). This will remove streaks and prevent white salt stains.
And for carpets, sprinkle fine salt, leave for an hour, then vacuum - the pile will become brighter and the odors will disappear.
