This is a simple and visual guide on how to prepare a chlorine solution to disinfect surfaces, floors, toilets and other objects. What you need? A ventilated space? A pair of gloves? A pair of goggles? A mask? And protective clothing such as an apron to protect your skin. You need some tools, plastic buckets and plastic spoons. And the products you can either use powder or granulite chlorine, such as calcium hyperchlorite, also called high-test hyperchlorite, HTH, ideally with a concentration of 70% of active chlorine. In absence of HTH, you can also use chlorine tablets such as aquatabs or liquid solutions of chlorine, such as sodium hyperchlorite, bleach or chlorox. Finally, you will need clean water for the dilution. Whatever the choice of the product above, the goal is to produce a solution with 0.5 of active chlorine, which will disinfect floors, toilets and other objects. We are going to show you the process to prepare this 0.5 chlorine solution from the HTH 70%. First, get dressed in your protective clothing and go to a ventilated place. The process to prepare the solution is very easy and is done in three steps. Step 1. Pour one liter of water in a plastic bucket. Step 2. Add one tablespoon of HTH, the equivalent of 15 grams into the bucket. Step 3. Add one more liter of water and stir well. You now have two liters cleaning solution with 0.5 active chlorine in it. You can use it for cleaning floors, toilets and surfaces. Be careful. This solution is very strong and efficient. Therefore you must wear protective clothing to prepare and as well when you use it. If you need to store it, make sure it is kept in a dark place and for no longer than four days, otherwise the efficiency of the solution will rapidly diminish. During epidemics or pandemics, we recommend disinfecting with such solution. Hospital wards at least three times per day. This floors and surfaces at least once per day and toilets at least twice per day.
