Best Practices –  

  • Be sure to read and follow the instructions on each bottle. 
  • Don’t over use. Estimate the proper amount of product for the size cooling system you  have. Adding extra amounts does not make Irontite “work better”. 
  • Flush with water frequently between processes.  After using Thoro-Flush and again after  using Ceramic Motor Seal, it’s best to flush the cooling system with water.  Because no  cooling system can be completely drained, by flushing with water you further dilute the  remaining product and get your system better prepared for the next process. 
  • Use protective materials and fender covers to keep any splashing or drips away from  chrome and painted surfaces. 
  • Proper flushing may reveal more leaks than originally seen as hardened rust and sludge  are dislodged from potential leak areas. This is normal and will allow the following steps  to further permeate all areas for long lasting protection.
