    Can anyone recommend a brand of clear silicone that will not turn yellow or at least not for several years please?

    In our bathroom we have clear silicon around the glass wet room shower screen, it runs along the floor and up the wall to seal it, it was professionally installed and the silicon remains clear after 7 years.

    In contrast to that, I have used some of my own clear silicon to fix a glass shelf in place and to also seal around a few other things in the same bathroom but the clear silicon I've used quickly turns yellow. I have replaced it almost annually each time using a different brand of clear silicone and yet it still turns yellow and I'm tired of having to repeatedly re-do all the silicon every year.

    Obviously there is a brand out there that doesn't turn yellow because the stuff used on the shower screen still remains clear after all this time, despite being the most likely area to first turn yellow or black but I've been so surprised that its a clear now as the day it was first put in. I've tried to contact the person who fitted the bathroom to find out what they used but the company told me that the installer who did my job would have used his own products and has since retired so they cant ask him, typical.

    So, if anyone can please let me know the secret of what brand of Clear Silicone to use so as not to get yellowing, I would would be extremely grateful.

    Look forward to your replies.

    Thank you.

    I had some success with CT1 in a kitchen.
    Cannot vouch for it now.
    12 quid so very expensive.

    I used some in a shower area recently and it went yellowish fairly quickly. Not sure if that normally happens with it tho but I was surprised cos it’s good stuff.

    I would try Dow Corning 785 clear silicone myself if u haven’t already.

    Thanks, I've not tried either of these but if its possible the CT1 does go yellow in a shower environment and the fact its twice the price I might try Dow Corning 785 Clear first to see how I get on.

    Thanks for these suggestions.

    I welcome any other suggestions from anyone else.
