ZINC BLACKENER. 25ml trial size


A room temperature blackening process for die cast and plated zinc surfaces. The very mild acidic liquid concentrate is diluted with 9 parts of water for a 10% by volume working solution. Immersion times of 2 - 5 minutes. Equally effective on cadmium surfaces. 16 fl oz.


Surface Preparation




Older zinc die castings (pot metal) should be blast cleaned with either glass beads or baking soda to remove the oxide layer. Some parts may not blacken evenly. In this situation, blast off the defective coating, then ‘etch’ the metal by immersing in a solution of 5% battery acid and distilled water for 60 seconds. Thoroughly rinse in fresh water, then repeat the blackening process.


To blacken the parts, simply immerse in the made up solution until uniformly black. Agitate the parts to remove air bubbles etc.  Rinse the parts in fresh water and allow to dry. Do not handle the parts for at least 1 hour.   Seal the surface with  metal sealer or Beeswax/wd40

Good product.
Color: Black, Item Shape: Classic
It is helpful for sure. I had knee surgery and this helped me keep my knee comfortable while working. I wish it was able to raise my leg up a bit more but for the price this is fine.

Great for short peeps!

the best for a too tall desk or table or not correct height chair. 5’3, always too short for things and this has definitely helped since working at home! super soft too and different surfaces and heights!

helps my swelling in my ankles and feet
Color: Black, Item Shape: Classic
I was having issues with my feet swelling because I sit all day for work. After using this my feet don't swell like they did. The product is also comfortable. I would recommend this foot rest. The best part is its two and one. You can use the rest or turn it over and rock it with your feet which helps. The foot rest is sturdy and durable.

Very Comfortable & Useful Foot Rest
Color: Navy, Item Shape: Teardrop
This product is a lifesaver for me since I sit at my desk for hours on end. Just the simple act of raising my feet up onto this heavenly soft foot rest makes a huge difference in how my back, legs, and feet feel at the end of the day. Very high quality materials and workmanship. You can also remove the zippered cover from the memory foam pillow and wash it.

Very Comfortable and Supportive, Minor Flaws
Color: Gray, Item Shape: Classic
I’ve been using this ComfiLife adjustable memory‑foam foot rest under my desk for a few weeks now, and it’s made a noticeable difference in how my legs and lower back feel. What I Like: The high‑density memory foam is plush but still supportive, conforming nicely to my feet whether I wear shoes or sit barefoot. Under Yours +2 ShipItFurniture +2 The adjustable height feature is super helpful — you can add or remove a base layer (2-inch detachable bottom) to set the footrest exactly where you want it. ComfiLife +1 The removable cover is machine washable, which is great for keeping it clean. Under Yours The bottom has a non-slip rubber surface, so it stays in place nicely under my desk. ComfiLife It’s multipurpose: you can even flip it over and use it as a rocker or support it under your knees. Under Yours What Could Be Better: Because it’s memory foam, it compresses a bit over time—not a deal-breaker, but you’ll notice it loses some height after prolonged use. ShopSavvy While the height adjustment works, I found it a little less stable when fully extended. ShopSavvy The fabric cover can collect dust or dirt, so you might need to clean it more often than a plastic footrest. Fakespot Overall: This footrest is a strong pick if you spend a lot of time sitting at a desk and want something soft, supportive, and adjustable. It’s not perfect, but the comfort and ergonomic benefits are absolutely worth it.
