Derivan Screen Cleaner is your solution for effectively removing Derivan Screen Block Out from your silk screens.
Begin by generously applying Derivan Screen Cleaner to both sides of the screen with a wet sponge and allow it to sit for five minutes. This period allows the cleaner to penetrate and break down the Derivan Screen Block Out, loosening it from the screen mesh. For added assistance, place a wet cloth over the screen.
After five minutes, utilize an old toothbrush to gently work on both sides of the screen using small circular motions until the Block Out is completely removed. In case the Derivan Screen Block Out has dried on the screen for more than five days, you may need to repeat the process several times to eliminate all residue.
Finally, rinse the screen with cold water and leave it to dry.
Remember to wear protective clothing, eyewear, and gloves when using Derivan Screen Cleaner to ensure your safety during the process.
