Silicone tubing gone bad

[dcalnan]

I was about to put on a brew earlier and discovered that my silicone tubing for my chugger pump has all gone yellow, and it has a white powder on the surface and a really chemical smell. I only used the tubing once and it was all cleaned and air dried after. One bit of tubing that was in the same box hasn't gone yellow at all. I bought it from unitedsilicone on eBay from the UK.

The picture compares the two colours, I'm worried as I have ~20m of the stuff and I don't want it all going bad.

My silicone tubing is yellow also, it goes like this after a couple of uses and is nothing to worry about. However there is no chemical smell off of it and I have it about 15 months. Can you remember what you washed it in? Oxi will leave a white powder if not rinsed off

Initially I cleaned it in ICU to rinse off the powder from manufacturing, after the brewday rinsed with oxi and then hot water, and let to air dry, the other bit of tubing had the exact same routine but was only used for transfer to the fermenter, I  think the smell is possibly the peroxide from the tubing as I don't think they're platinium cured.

I bought some from ebay and got the same powder coating after cleaning it. I think it's shagged.

And I have 20m of the stuff  ,might email the manufacturer.

It sounds a bit dodge. I rinse mine in oxi after use. Got mine from brewbuilder it's good quality I would get back onto the seller
