Why yes, some of the disinfectant cleaners from the PriceCheck search results would be suitable for cleaning outside surfaces as well. The Citrus Antibacterial Floor & Tile Cleaner at only R29.99 for 750ml is a great budget-friendly option that can be used on floors, tiles, and other hard surfaces both inside and out. The Mr Muscle Multi Surface Disinfectant Original is also affordable at R52.95 for 750ml and works on surfaces throughout the home or garden. Both of these concentrates provide antibacterial cleaning and disinfection to kill germs wherever you need it. Just be sure to test them in an inconspicuous area first if using on any surface outside. I hope one of these options works well for your outdoor cleaning needs!
