Motorcycle Exhaust Cleaning - Fast and Cheap!

This video is similar to what others have done in Europe using Harpic Power Plus 10X (hydrochloric acid), I wanted to do a video using a similar product found commonly in the US. I used Zep brand (Lysol or Lime-Away are also similar) toilet bowl cleaner with Hydrochloric acid so you have to wear gloves and eye protection! Also ensure you have proper ventilation and water handy for safety and cleanup.

A word of warning : Although the internet is full with advices to use Harpic Power Plus 10X to clean a stainless steel exhaust, I would strongly advice not to. It contains hydrochloric acid and yes it will clean and penetrate the stainless steel surface impurities, but at the same time it will destroy the surface of some stainless steel products that don't contain enough chromium to form a new passive protective layer. So in the end the cleaned surface will start to oxidice very quick and you do not want that. hydrocloric acid is the one acid that should NOT be used on Stainless steel, it actually destroys its capability to reform a hard chromium surface that prevents it from corroding
There are far better, safer products like welders pickling paste , that use milder nitric acid used in passivation solutions. They come in a paste form that is brushed on. Let it sit for half an hour and rinse very thorough (high pressure would be good) with a lot of water. It will clean and decolour the surface perfect and it won't harm the surface of the stainless steel. It is used by welders to clean the coloured and contaminated welding surface on stainless steel welds
Just to give a bit of warning.... You shouldn't believe me, search the internet on hydrochloric acid vs stainless steel..... Do the same on nitric acid.( Just don't let the nitric paste come in contact with aluminium.)
And one more thing : It is even stated in the Harpic Power Plus product safety data sheet : Reactive or incompatible with the following materials: metals
