the powder in the US is made for top loader- I also have an American top loader in the UK, and find I have to use more of 'our' powder than I would in a front loader. That, I am told, is because top loaders need suds and agitation to wash well, whereas front loaders are the opposite - suds would be a disaster.
Anyway, in the UK we are supposed to use Handwash powder or powder made for top loaders............I just double up.
Anyway- THAT is why you shouldn't take powder with you- it won't work as wellTide is good over there, and Sun.
