Dishwasher powder works well , some advise using the dishwasher .

A cut down tooth brush head on a wire coat hanger worked for me.

Chuck it in the dishwasher

Alloy wheel cleaner, CarPlan, comes in a silver and black box, or use a pressure washer.

Another vote for the dish washer.

:cough: Dishwasher :cough:

(just in case SWMBO reads this)..
I guess the powder + "cocktail shaking time" would do just the same job, but the dishwasher is less effort...

this has been asked at least 2 x previously so a search will give more ideas.

my suggestion is to use sme detergent then put a few glass beads or ball bearing, seal up the tank and shake.

very often the plastic itself is stained so it wil never become transparent.

buy a new one!! thats what i did
