Optical Brightness Restorer
 
 DroGo A is a blend of liquid optical brighteners used to restore brightness to dull fabric. Fabric must be clean and stain-free before DroGo A is applied (residual stains may become more visible if treated with DroGo A). DroGo A is often used with DroGo B and is included in the DroGo Kit.
