They are cheap to get new. If they are not yellow, you can soak them in a good degreaser and hot water. The coolant bottle gets funky on the inside, and is hard to clean.

I degreased mine...and.....
Like Forcefed says.. I scrubbed them in and out then trimmed the jagged edges left along seams when they were shot in the mould. I added a second long bath in hot water and bleach. The came out kinda very light tan...not bad. I cleaned the caps - repainted the lettering - flushed the systems - added clean bright and fresh fluids and hey they looked fine. If you got a show car replace'em or for the special show just replace for that. Otherwise they will start the yellowing process all over again. My 2 cents.
