Osmo Silverising Shampoo 300ml

Product is great, packing was so-so. It leaked in transit and this stuff is PURPLE and I have white/birch colored kitchen cabinets. Sealed with a piece of clear tape and the screw top cap didn't seemed to be screwed on too tightly. When I opened the package I somehow got some on one of my cabinets and it didn't look like I was going to be able to remove it. Yikes. It finally came out, although every day I look at the spot and think I see a purple shadow. As for the shampoo, yes it will help remove any yellow buildup.
