I can't tell you how to get rid of the stuff, but orange in a bathtub is a very bad mold. It is the same mold you sometimes find in potatoes in the ground. I think it's called something like "Stacchibotytritus"(not sure of spelling). It is actually dangerous to humans. Hope someone else will tell you how to get rid it it. Wishing you good luck!

You don't mention how you get your water but sometimes if you have a water softener, you can get orange "rust" deposits. I know I used to have that when I had well water (higher iron content) and a water softener. I'd get your water tested first and then check into whether or not it's a mold, as jannie indicates.

Thamks all! I will try to post a picture....but now I'm nervous! If someone could please tell me how to get rid of it, thhat would be great. My water is city water, and i don't have a water softener....i've had the water tested and the ph is a touch high, but nothing dangerous.....

1. Orange deposits are generally from high iron concentrations in your water, CLR or scouring will get rid of them fairly easily. TO mitigate, try an ion exchange (water softener is one example) unit for the whole house.
2. Orange mold is more rare, but a basic cleaner, like Tilex, will generally remove it.
3. Orange deposits are sometimes caused by makeup residue.

It definitely sounds like mold. We have the same problem in our shower. I use a 50/50 mixture of bleach and water to clean it. Unfortunately, without regular bleach cleanings, the mold will begin to grow again. You will need to continue to run your "bleach baths" every so often to keep the mold at bay. As for the filter, if you can remove it from your tub, I would soak it in a 50/50 mixture of bleach and water. If not, fill the filter area with the mixture and let is soak for 15 minutes before you run your bleach bath. Mold sucks, but with proper maintenance, it can be controlled. Good luck!

I just moved into a house that has the same issue with a 10 year old Jacuzzi brand jetted tub. I had another jetted tub (not jacuzzi) and it did not have this issue. The orange stuff is called Pseudomonas aeruginosa (my wife is a micro-biologist) about once very two weeks when you are finished with a bath pour a 1/2 cup of bleach into the tub and run the jets for about 10 minutes no more Pseudomonas aeruginosa. Best to not do the bleach treatment while soaking for obvious reasons.

We have the same problem. We had the city come out to check the water and it was fine. Our jets do not work too. Is this also Pseudomonas aeruginosa? Is it dangerous? Here are some pictures, it's actually orange rust color but you can't tell in the photo.
