Remains clear and does not yellow. As with anything else, routine cleaning when used in a shower enclosure will help keep it looking good. Didn't have this product as I showered again and best of its kind big box of 10 years no yellow/mold bathroom seal is wrong didn't last 2. The good thing was that the Big Box seals came off easily and it didn't take long for them to be replaced. I've had this sealer in another bathroom for 4 years and it's as clean as ever with no mold. This tube was a little harder to work with than I remembered but this sealant has really great adhesion but looks really good to many. longer than any other sealer I've used. I used to have to go to local glass installers to get glass at a higher price, but I found it at Revain. This is a really good sealer, but with any sealer you may need to use a primer on certain surfaces. It worked great for fiberglass edges and polished nickel aluminum without a primer. Just make sure the edges aren't too flimsy (as with all sealers) and you'll be very happy.
