I've just bought one of these from Aldi too. They have about 7 or 8 of them left at the Nacton Road, Ipswich Aldi. £17.49.
It's actually identical to the Ultra 7000 model sold by Maplin for £45!!
. They're also on eBay too, just search for 'Ultra 7000'
. Another name they appear to go under is JPL 7000.
Maplin also have the Sea-Clean solution for £4.99.
So far I've tried using just water alone, and the results are pretty ok. If you want to test yours' then get a bit of tin foil and lower it into the solution, it'll start to disintegrate. :rolleyes:
Usually I use bleach and a toothbrush, and for things like retro computer keys/small parts I put them into a cut off leg from a pair of thick tights, and put them in the washing machine with the weekly wash.
Are there solutions that we could make ourselves to use in the unit?
