So, I thought I would make a quick and above all cheap cleaning solution.
Parts required are simple:
some metal scouring pads
A knife of sorts
A pen for detailing
Total cost was 59p
Step 1: Prepare the Box
Then make a hole!
Mind your fingers ;-)
You have a couple of choices here, put a counter weight in the bottom of the box to allow hands free scrubbing or as I did simply pack away.
Put the scrubbing pads in the end nearest the hole and pack out any space with cardboard. Just try and avoid using anything that will melt.
Tape up the box and decorate if you feel the need.
Step 2: Cleaning
Stick it in the hole and give it a good scrubbing.
The good news is that you won't burn your hands and you end up with a shiny tip ready for action.
Have fun :-)
