That layer is really tough to get through, but once you do it's easier to go through the raw metal. Any metal-etching solution should be fine for aluminum, just takes a reasonably strong acid.
Just for kicks, try using de-fizzed Diet Coke, I think it has a pH of around 3. That won't be as strong since it already has stuff dissolved in it, but it'd be quite the ghetto trick.
Etching aluminum with acid is not that good of an idea. I know friends that use the same etching acid for writing on stuff and when it is applied on aluminum it just looks nasty. Most plastics are pretty resistant to acid, so i seriously doubt that a store bought etching kit for glass shouldn't have much effect on plexi.
It might make it cloudy but it shouldn't eat it away. The reactivity of an acid is more of a factor to how well it reacts with objects than PH is. Were I work we have many differnt kinds of acids mostly in the 0 to 1 PH range.
The react very differenty when compared to each other. But put titanium in the same acid and it goes very quickly. If I was to etch plexi I would go a differnt route. Leave the protective coating on 1 side and cover the entire other side of the plexi with stencil of the pattern you want etched.
Expose the whole thing to acetone fumes or using a lint free cloth with a little acetone in it lightly blot the area of the stencil to be etched. The acetone will melt the surface of the plexi and leave it with a rougher texture and a milky color. Apply a drop of Armour Etch to a scrap of your acrylic sheet and see if it reacts. If it does , you have your answer; just mask off the acrylic , cut out your lettering and apply as you would on glass. The materials that the laser can cut materials like wood, paper, cork, and some kinds of plastics.
Etching can be done on almost anything, wood, cardboard, aluminum, stainless steel, plastic, marble, stone, tile, and glass.
It will not noticeably affect stainless steel. Plain white vinegar is what you want, but any vinegar will work. Making a blade darken quickly is called a "Forced Patina". As with all patinas, it is only oxides on the surface, and will rub off in sanding and in use.
The Cricut Engraving Tool also called the Engraving Tip is designed to inscribe into your material like metal or acetate and create an etched, permanent imprint. It does this using a tiny metal point which is pressed into your material. Glowforge can cut wood, fabric, leather, paper, Plexiglas acrylic , Delrin acetal , mylar, rubber, Corian, foods, and more. Glowforge can also engrave all of the above plus glass, coated metal, marble, anodized aluminum, titanium, some phones, tablets, and laptops, and more.
Loving the new Cricut Maker and using my engraving tool to engrave some balsa wood signs. These would make some great garden signs for your garden.
Use Etching Cream to permanently etch your own designs and lettering onto glassware, mirrors, porcelain, and ceramic surfaces.
Simply cut out a custom stencil from Stencil Vinyl using your Silhouette cutting machine then and apply Etching Cream to create permanent and beautifully etched designs. ABS does not cut well in a laser cutter. It tends to melt rather than vaporize, and has a higher chance of catching on fire and leaving behind melted gooey deposits on the vector cutting grid.
Cutting ABS plastic emits hydrogen cyanide, which is unsafe at any concentration. Stainless Steel is not an easy crafting metal. Now, if you're fortunate enough to own a Cricut Maker , you can personalize your engraving designs. Apply a couple of drops of Pinata Tint to the sponge and blend a little. Wipe the tint in one direction over the top of the white etching. Clean up the excess with a drop of clean up solution on a cotton swab or paper towel.
Squeeze a daub of white Rub N Buff into a mixing container. For a nice permanent finish, you can use paint specifically made for glass. Asked 3 years, 4 months ago. Active 12 months ago.

Well, I tried applying it the same way I would etching cream and made a big mess. Improve this answer. Allison C 3, 10 10 silver badges 29 29 bronze badges.

You might also be able to make a paste with acetone and something it won't react with, like baking soda or powdered chalk — Chris H. If you are too impatient to vapour etch, you can use a fine atomiser spray.
When finished, the wax can be removed using very hot water. Gwyn Gwyn 3 3 silver badges 7 7 bronze badges. Henry Taylor Henry Taylor 2, 7 7 silver badges 14 14 bronze badges. Hydrofluoric acid will do little to any plastic. It will eat glass, titanium and skin. I would not experiment with it. Sign up or log in Sign up using Google.
