I'm hoping someone can help me. I recently moved into an apartment where the white silicone sealant around the bath, shower, etc had patches of deep yellow in it. As this bothered me, I went ahead and removed it and resealed with fresh white silicone sealant. Within 3 days there is a definite yellowing happening in the same areas.
What could be causing this? Is there an alternative product I could use to avoid this happening in the future?
