Review on Vanish Drop Ins Blue Pack 12 by Christopher Yap

I bought this mainly to make the eau de toilette blue because I use other products to keep the bowl clean (Clorox & Kaboom tablets). blue, right? you could fool me! Did! Not even a tint or hint of blue! But as I was writing this, I realized WHY! Edit: Ah! I was right. I removed the Clorox and Kaboom tablets and BAM! Awesome BLUE! Only thing is they don't clean porcelain nearly the way chlorine based tablets do. 😦 Clorox tablets and Kaboom tablets for Vanish Blue dye stains!
