Thank you!!! I find this video super useful as I ride all year around with plenty of salt in winter and always struggle to clean the exhaust pipes headers.
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
Not sure...don’t own the bike now 😆. It looked fine but on this bike the exhaust is very open and it didn’t stay clean that long. Let’s face it these are to be ridden not looked at. 😉
Try covering most of the engine in Vaseline when you first get it, then wash it off when you want it to shine...mine is 4 yrs old too and looks like new (almost)...ridden 365, but have to admit to not doing as many miles as yours...great bikes!!!
Hey can u please help me out ,,I have a benelli TNT 600i ,I used the harpic blue version ,not the bleach ,but it turned out to be awsme ,but just the next day took it for a ride and it turned almost golden ,so can u tell me how long did urs last ?As I feel if the harpic works only on the day applied then it's a useless hack
ADITYA HABBU I wouldn’t expect this to be long lasting but mine certainly retained its shine for a good couple of months. I suspect the type of metal used for the exhaust, location and conditions of roads can be a factor.
Yep, although have tried to degrease the engine and clean it in the last month or 2. Also some elements of the engine (alloy case) paint is starting to come off.

What would be a good concentration of nitric acid for good results as most people won't be able to get their hands on any high concentration.
I have seen some other TH-camrs briefly heating the exhaust pipe until warm before application.
my god you work fast.......like superman
Spray my dl with WD40 then l can hose off salt and crap during winter riding...an nothing rusts...
Thanks for the video
And how does it look now? Rust comes back faster doesn't it. Did you have to buy new headers?

So cover the engine in vaseline when you first purchase?
Are you the 3rd member of Wham?
Harpic forever!!!! Perfect!!!!
Very bad idea
I did this to my zrx1200s on the Wales on frame and other parts to good job but clean it off properly use a brush
have you tried autosol? as a finishing step?
Richard Ricketts not yet.
If you add it pure on it, and scrub it after sitting, gona work much better and easily
Cal Sa you can do but the way the head/s are they any liquid will just run off hence my dabbing approach.
i like cream clean but harpic does good job thanks

add engine oil please
Engine oil was fine, the angle is not the best though.
Wish I have to clean just one pipe 😈
should pour it into the cap and paint it on with a brush. Sponge was crap way.
coppermine64 you can do, everyone has different ways of delivery, but the sponge was effective, using the back of the sponge was more so! 😊
Did you speed up your 'Dabbing'
Negative.
Harpic eats metal. I use drdownpipe
Cleaned the exhaust and not the rest of the engine, really?
Yep, although have tried to degrease the engine and clean it in the last month or 2. Also some elements of the engine (alloy case) paint is starting to come off.
Bad...hydrochloric acid is bad for stainless steel. If it's easy to clean your bike with toilets product when will you poo on it?
Ppkoo
