So you thought cleaning stainless steel grids was a difficult job...
Well watch these videos and see how easy it is if you have solid stainless steel grids from Botany Stainless Steel on your braai.
Stainless steel is an all the way through material, which means that you cannot scratch through the surface coating and expose the under surface materials that will rust.
Botany Stainless Steel Grids are made in food grade 304 stainless steel bars so there are no layers or coatings, just solid hygienic food grade stainless steel all the way through.
The majority of grids are made in mild steel and chrome plated, which effectively will give a coating of a few millionths ( microns) of protective steel to the grids, and which can be chipped or scratched off the grids with washing or normal wear and tare.
Well once you upgrade to stainless steel that will be the end of this problem for you, due to the ease of cleaning stainless steel.
