This is more of a product review and the results that it can provide instead of a DIY but its self explanatory once you get the product.
Got this product a week ago and today it was a nice day to test it out. Yes the car is very dirty next week it will get a wash

This product does take off the baked on black carbon deposits but it will require more pressure and time to get it off but it will do it. Next week i will do a full cleaning of the tips and post more results.

 

Oh my god wash your car right meow. If you got time to polish your tips and make a 1 step tutorial then you have time to wash!

 

Nice results

 

Snowing on Tuesday and Thursday too much work to wash it and then let it get dirty again. Next week it will be all clear

Thanks!
