How to clean a car tank so it looks like new

When pre-selling a car or simply for your own aesthetic pleasure, you may need to wash the yellowed expansion tank. When it is clean, the engine compartment looks more cheerful and fresh, you can immediately see that the mouse has been looked after. A regular brush and water with powder will not bleach it. Let's look at how you can wash the tank to perfection.

What you will need:


  • insulating tape;
  • any detergent;
  • sulfamic acid (H3NSO3);
  • Sonax cleaner or similar.

      No, not for sale... it’s simple, but plastic tends to break down due to temperature changes, I glued it myself, but the color doesn’t affect the speed!

    Have you personally tried this method?! People who have tried it personally claim that it doesn’t work.

    Having worked in auto parts and going through my car, the thought comes to my mind that the original video of this article is a hoax. We have two tanks: old and new.And we remove it as if we were taking out a new tank from colored water.
