Problem keeping reservoir clean
#1
I'm using a Resperonics REMstar Plus C-Flex 250P with it's heater humidifier, and have been using it since September 2011.

Lately I've been having a problem keeping the humidifier reservoir clean. I soak and clean it with a little Dawn dish soap in warm water, and every so often in the dishwasher. I only ever use it with distilled water. The next evening I look in it and see stuff(?) in the water. There is also grime on the heater plate - especially visible if you touch it.

The first time this happened I cleaned it and changed the filter, but it was back the next day. I'm also using one of the thin white filters with the dark grey foam one that fits in the recess on the back of the unit.

I've also removed and cleaned the round silicone seal that fits in the lid that closes on the top of the reservoir as well as the ones that seal the reservoir to the unit.

I have a small flashlight with a 24 LED floodlight on the side (it's really bright) - the face is about the size of a credit card. I hold it up against the side of the tank in the dark and anything in there is very visible.

The seal between the halves of the reservoir are ok and I'm pretty sure there are no cracks. When I hold it sideways with water in it, if there were cracks or any part of the seal was bad, it'd leak, and it doesn't. I think the seals are silicon and should probably outlast the machine.

The top pic here is before use, filled to the line, and the second one is the next morning (I forgot to put the black piece of plastic under it in the 2nd pic).

Any thoughts as to what that stuff is or anybody have a cure?
Note: When posting this I haven't been with ApneaBoard long enough to post images or links. If the pics don't show up, just add in the http stuff and get rid of the space.

Update: Yesterday I soaked it in warm water and a little Dawn for about an hour, and then into the dishwasher it went. The top pic was after it dried out, and the bottom one is from the next morning:

G'day Stanstr, welcome to Apnea Board.

To help clarify your problem, do you use distilled water, filtered or tap water?

Stanstr, replacement System One reservoirs are inexpensive at around $22 or $23. If you want to clean up the one you have, you probably need to disinfect it. White distilled vinegar does a good job. I recently posted I use a brewery disinfecting solution called Star San, just because it's around and works well. The vinegar needs to sit a while and then you'll need a toothbrush or similar way to manually clean the many nooks and crannies in that tray. It will solve your problem.

You may be due for a replacement machine soon. Try not to get stuck with a CPAP that does not provide data like your current one. Anyway, you might want to start getting your prescription in order so it is ready when you are.

I only use distilled water.

When I put it together the images showed up as I expected. When I clicked to post the thread, it told me I can't post "...clickable links to this forum threads and posts. Minimum post count is 8 posts. But your post count is just 1 posts. You are not allowed to post images in this forum."

I saw the page about working with attachments. Maybe I should have tried that instead of using imgur and linking.

I wrote a board Admin, and was told to post it as a broken link, tell him and he will embed the images.

Thanks for your reply.

The thought of putting a reservoir in the dishwasher does not sit well with me, after cleaning my dishwasher over the yrs.
Dishwasher soap is a very good cleaning agent, pick a large bowl and put a little dishwasher soap with vinegar & hot water in and swish it around for a bit and it should clean it. let it soak for 1/2 hr.
Rinse and air dry should give better results.
If you are not happy purchase new reservoir or new brand of distilled water.

Everyone else:

I made a mistake in the 2nd pair of pictures update: I wrote "The top pic was after it dried out, and the bottom one is from the next morning", but it shoulda said that the top pic is before use, filled to the line, and the second one is the next morning.

Thanks, but I have used white distilled vinegar - even though the instructions make no mention of it. The book says,
"CAUTION: Use a mild dishwashing detergent only for either hand washing or when using a dishwasher."

It is also a difficult thing to clean out - it has a lot of corners. I took a toothbrush and heated it just behind the head so I could bend it at about a 70 degree angle - works nicely, but still a bit big to get in everywhere.

I've never heard of Star San, but I like the Amazon description, "...a blend of phosphoric acid and dodecylbenzenesulfonic acid. This synergistic blend provides a unique killing system that is unaffected by excessive organic soils." Also, wikipedia says "Billions of kilograms are produced annually." A unique killing system? Billions of kilograms?

I am looking at other CPAP systems as I think I should be getting a new one maybe later this year. I was looking at one with an exposed water tank, the Resmed S8. It looks like it'd be easier to clean, but I'd have to see one in person, and figure out the pluses and minuses.

The CPAP I'm using has a SD flash card for data.

My previous machine was a Puritan Bennet Goodknight 420G. The bottom came off the tank and it was much easier to clean.

The S8 systems are old and you cannot view the data from their proprietary card without a special smartcard reader (not the same as an SD card reader).

Is that stuff in the water or on the surface of the water?

Where do you get your distilled water?

Have you tried switching brands of water?
