Precautions when using water oxygenated Once sandpapered the wood surface, extends on the same the chemical compound with a white rag. This it does not have to be of cotton, since this material is degraded with facility by the action of the oxygenated water. Spent minutes, the zone dealt with a cotton rag rubs with energy.

If the result is not the hoped one, it is possible to be repeated the process past hours. The volume is the measurement that is used to identify the concentration of oxygenated water solutions. In this case, 1 volume is equivalent to an oxygenated dissolution of 0.3% of water (H2O2) and a 99.97% of water (H2O). If one considers that the water oxygenated that is used with medicinal aims and disinfectants have 10 volumes, the reason will be understood by which, when using this product to a greater concentration ten times, is obligatory the use of gloves, mask and protective goggles, since the risk of burns poisoning is high.
