Those were the days before plastics invaded planet Earth. Remember these brushes ? Let me share a blast from the past.
They were used by practically every household for scrubbing laundry, kitchen sinks, floors, dishes, shoes, etc. The brown ones were softer than the black ones. The latter were used mainly to tackle stubborn stains and deeply-entrenched hardcore grime from all kinds of surfaces.
I learned that the brown ones were made from coconut tree fibres – can anyone verify that ? Am not so sure what the black ones were made of.
For some years these organic, environment-friendly brushes became scarce as cheap plastic ones flooded the market. But lately, I notice they are making a comeback. Not only in brown and black, but even with stripes.
