Yes, work on getting your dye to dissolve better, and then strain it. There are tips under
MX Jet Black, including this paragraph I wrote:
Mix the dye by adding a small amount of water to your dye powder and stirring to form a paste, then gradually add more water while stirring. Leave the dye mixture to sit for a half hour or so and then stir some more. Instead of a spoon, try using a blender, or an immersion blender, or a whisk—but note that none of these tools should be reused for food after you have used them with dyes. After the dye is completely dissolved, it's a good idea to filter it through a nylon stocking, to remove any clumps. You can add a single drop of Synthrapol or hand dishwashing detergent to aid in dissolving the dye powder. Do not use hot water to dissolve MX dyes.
It should help some.
