Thanks petemacsydney, Just put on on order from ebay.
I did a search and found this on youtube, https://www.youtube.com/watch?v=99kGy8-bGXs
It looks like the lymans solution is not as good as the water, vinegar, salt, detergent solution. I have seen that recipe on other web sites also, see below. Obviously it would need to be scaled down for a 600ml US Cleaner
Hot water 4 parts (Cups)
Vinegar 1 part (Cups)
Dish soap-detergent 1 table spoon
Salt 1 table spoon
