If I bring my own soap, do the machines take HE and can it be liquid?
All washers can take HE soap, it is HE machines that can't/shouldn't take normal soap.
So you are fine using HE detergent in the washers. It can be liquid. We bring the HE version of Tide Free and Gentle Liquid Laundry Detergent with us; I put some in a nalgene bottle (which is leakproof) and bring a small plastic dual measure (1 tsp / 1 tbsp) measuring spoon.
Some tips:
- the detergent dispensing tray can be removed and cleaned; if you have a strong preference for your own detergent, I suggest gently taking it out and cleaning it -- the packs they sell are powder detergent and people put them in the dispenser instead of the drum and the powder does not fully dissolve... it is gunky in there !
- the liquid "pods" are too much detergent; there will still be suds at the end of the full cycle; we learned this the hard way our first cruise and have only brought liquid detergent since; (if you don't watch the last bit of the cycle you may not realize there are still suds - even with just using a teaspoon of detergent we still have to do a second full cycle to get a sufficient rinse)
- the washers are SMALL so you can only fit a small load; you need to adjust your detergent accordingly otherwise you will have suds left
Another option to consider, that we have started to do on our cruises and for travel is that we bring a Scrubba wash bag with us and try to use it to wash clothes, then the dryer or air dry (depending on item). Doesn't work for everything and it is annoying if you have a bunch of things to wash at once, but I find if I keep the # of things managable it works well and ends up saving time, though is more work.
