How to safely clean silicone lining in aquarium?

[AJ_117]

Good evening everyone, I have a little bit of algae in my tank and usually use a magnetic bristle to clean the glass, however I've noticed that if I brush too close to the silicone seal, that it'll rip off small pieces of silicone. What is an effective method for cleaning on and around the silicone without damaging it? I've thought about getting an ultra-soft bristle toothbrush but I'd like to know if there's a better method. Thank you in advance.

I tend to either run my finger down it and find that surprisingly effective or a soft cloth. Interesting question, you would think there would be some gadget for this
