So i recently completed a bathroom renovation and i have found the clear silicone around the bottom of the bath taps (in a shower bath) has gone yellow within about 3 weeks.
The same clear silicone used elsewhere in shower bath area hasn't discoloured, literally only around the taps (also gone yellow under the sink tap which is the same brand/model/design).
Link to photos below. 1st photo is the shower bar showing silicone that is constantly exposed to water and hasn't discoloured. 2nd photo is the taps where it has gone yellow
