In life there are often problems of varying degrees of significance. In any case, the impossibility of the solution creates some discomfort. For example, we bought the paint, opened a bank – the paint was thick, viscous. It is necessary to dilute! What? Painted with a brush. Need to take a break. What to omit at this time brush to paint on it is not dried up? Need to quickly clean hands, gloves, work clothes. How? Of course, for all occasions recipes can not be given.

Consider the most common situations. Initially, we denote the general properties of the commonly used organic liquids. First – they are fragrant. This, however, does not mean that the smell and harmful for the body – are uniquely related factors. There are many substances without odor (carbon dioxide, carbon monoxide) or with a pleasant aroma (sarin, soman), which in certain concentrations have harmful effects on the human body. Low molecular weight volatile liquid called solvents or diluents.

There are a large number of relatively accessible solvents – is gasoline (including the one in the tank of your car). Their common name – Nefras (petroleum solvents). We must bear in mind that Nefras to include not only gasoline. You can find the name of "petroleum ether" – it is petrol, too, but the relatively volatile (boiling point 40-75 0 C) or "white spirit" (Boiling point 150-200 0C). Higher boiling points have kerosene. But it's a liquid solvent with similar properties. They can dissolve or dilute the varnish and oil paints.
