Hello @brinkley 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your aluminium shower frame.

What you are possibly seeing are calcium deposits, soap scum or corrosion caused by chemical damage. I propose getting a green scrub pad and see if you can remove the stain at the bottom of your shower frame. If it feels smooth with the scrubber and none of it peels off, odds are the surface has been damaged.  

This sometimes happens when very strong cleaning chemicals are used. It strips the protective coating of the polished aluminium and delaminates the surface. You can try to remove the blemish with steel wool, but you will never get the original polish back.

If you need further assistance, please let us know.

Hello,

Can this trim be removed and replaced?

Hello @TonySmith 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about replacing your shower trim.

If you are referring to the plastic drip strip at the bottom of the glass door yes, it can be replaced. I suggest removing the drip strip so that you can compare it to the ones available at the store. As to the aluminium surround, it is integrated to your shower frame and replacing it would be equivalent to replacing your shower.  

If you have any other questions we can help with, please let us know.

Thanks for the reply Eric.  Yes we are referring to the Aluminium surround.  We were worried it was connected to the water stop or

waterproofing membrane.

Hi @TonySmith 

As I've mentioned earlier in the discussion you can use steel wool to remove the tarnish on the aluminium frame. You can also try to sand it using a high grit sandpaper such as Flexovit 100mm x 1m 600 Grit Wet And Dry Sandpaper Roll. Just make sure to sand in a straight direction and not in a circular fashion. Please note that it will remove the tarnish but will not restore the original shine of the aluminium. 

Please take extreme care when working around glass and remember to wear personal protection such as gloves, goggles and a mask when working on your project. 

If you need further assistance, please let us know.
