This product is manufactured in the form of a solution of 38% HCl (concentrated). Concentrations greater than 40% are chemically possible, but the rate of evaporation is very high, so storage and handling must be carried out in low-temperature. The most optimal concentration of HCl to the delivery of products is 30% to 34%. The content of hydrochloric acid on most liquid cleansers generally ranged from 10% to 12%. cleaning must be diluted first dahul
