Mixing Instructions: Add chemicals in specified sequence. |
Dilution: Use undiluted. |
Usage: Before use, test a small hidden area of fabric to ensure no bleaching occurs. Thoroughly wet the stain with this solution and wait for it to disappear (usually a few minutes). Old stains may require more treatments and require more time. Fully wash garment after stain removal is complete. |
Notes Keep thiourea away from all other darkroom materials to avoid fogging. |
