**This item replaces Ensitech's TB-40 Neutralizing Fluid**

After a period of extensive testing, Ensitech chemists have finalized development of TB-42 Neutralizing Fluid (for TB-21 and TB-25), an improvement on the popular TB-40 which has been used for many years successfully by TIG Brush owners worldwide. TB-42 Neutralizing Fluid enhancements include improved wetting agents for better coverage, faster action to neutralize the effects of TB-21 and TB-25 residues, improved solubility for easier removal with the final water rinse resulting in improvement of the final finish.
