How to Use: CLENESAFE RUST is diluted at 0.1%, 0.5%, 1.0%, 2.0%, 3.0%, 5%, and 10%, depending on the rust level of the surface to be cleaned. The appropriately diluted product is poured into a container. Rusted tools are immersed in the container, ensuring their entire surface is in contact with the solution. Wait a minimum of 5 to a maximum of 10 minutes. Any remaining rust and dirt can be brushed off with a medium-hard brush. After waiting the effective time, remove the tools from the solution and rinse with plenty of water. The effective time for ultrasonic devices is 5 minutes. It is suitable for use with cold and hot water. The prepared solution is usable for 24 hours. However, if the solution's appearance increases in dirt, replace it before 24 hours.
