Why you should NEVER mix cleaning chemicals

Many cleaning products are common and seem simple to use, however combining certain chemicals can be very dangerous. When your faced with a big cleaning job, it’s easy to just grab any product to try and combat it. But before you start reaching for any and every chemical, please reconsider.

It is a common misconception that if one cleaning product works then mixing it with other will make it work even better, but this is not the case. The frightening truth is that products which are safe to be used alone, can cause harmful fumes or other chemical reactions when mixed with other product.

 Bleach + Acid

Common cleaning agents like Toilet cleaner often contain hydrochloric acid, 2W06297which when mixed with bleach can create chlorine gas, this is a highly toxic substance and if this gas is inhaled the symptoms are shortness of breath and chest pain. This gas was also used to kill during the first world war, this is very dangerous and these two products should never be mixed.


Bleach + Alcohol

Mixing these two chemicals together creates chloroform (The stuff kidnappers use in films to knock out their victims) Although it may not make you pass out, the combination of these two chemicals can create this gas which can be toxic.


Drain Cleaner + Drain Cleaner

You should never mix two different drain cleaners or even use one straight after using another, the powerful formulas could explode if mixed together! If one product doesn’t work, never try the other product.


The bottom line is: never mix bleach with anything other than water. Even when the mixture of chemicals isn’t toxic, you can never be certain what effect two combined chemicals can have on a surface so it isn’t worth the risk.
