Cleaning washing machine pipes

Mumto2

In an effort to get rid of the smell of my washing machine (have done the filter, hot wash, soda crystals etc), I decided to dismantle the waste pipes. (Probably not my best idea at 4pm with 3 kids ).
The pipes are quite cruddy, although not blocked or anything. What is the best way to clean them out. They are the solid white plumbing pipes, too long to get a cloth in them.

I was thinking of filling the bath with a soda crystal mixture and putting them in there. Any other ideas?

Scuttles off to make kitchen safe before tea time.....

Update... pipes in bath, now wondering if I should just splash out on new ones. BUT bad smell in kitchen which I assume is from the waste hole. It goes through a cupboard, but have looked down hole with torch and it is dry (so think that is good news). Apart from a few drops of tea tree oil, I'm not sure what to do about that smell.

either replace them, they are very cheap. or insert a wire all the way inside and tie a cloth to the wire. then pull through.
just like cleaning a shotgun.

Physically scraping as much muck loose with a stick, bottle brush etc. will clean it best. Then pour some hot soda crystal solution through the rest of the pipe or some bleach.
Has the pipework got a trap (U-bend) on it. This should normally contain water and prevent smells from the drain getting back up the pipe.
If the pipe connects directly to a combined drain then the smell could be air flowing back from the sewer pipe.
If the smell is coming from the pipe work downstream from the trap then as long as the pipe is clear then it is not a problem and refitting the trap will stop the smell (after the first use, when the trap is filled with water).

Thanks all.

The pipe has got a ubend which was full of water when I dismantled everything, so good to know this will stop the smell.

The low temperature washes we do today dont help machines. To keep machines smelling good, I run a high (95 degree) wash once a month with soda crystals. In fact I use this wash as an ideal opportunity to give all my cleaning cloths a good wash.
White Vinegar is also great for removing the smells and I pour a mug full into the machine occasionally and again put it on the hottest temperature you have.
Hope this helps
