Spring cleaning: Allergy sufferers and asthmatics should pay attention to this. Cleaning with the windows open allows harmful fumes, residues from household cleaners and dust to escape.

Do not combine sanitary cleaning products with sodium hypochlorite and then an acidic chlorine agent. Wear a respiratory mask if you have allergies and Allergy Aid (DHA) are sensitive to the gas produced by these cleaning products. If you have hay fever, you should be careful as the pollen concentration in the outside air can vary depending on the time of day.
