Cleaning old plastic tanks

Tried to clean up some old tanks using Sulfamic acid (tile cleaner). came out pretty good. May try another round at higher concentration, but the original bottles were never "white".

Also, I ended up not doing the washer bottle as I couldn't find a good way to remove the motor and re-attach it leak-free. I used the same solution on the outside, and it worked just as well.
