WHY: When using a sprayer with most disinfectants, the aerosolization of the product can cause those who have sensitivities to cough. With regards to Rescue, it has been validated through third party testing to be non-toxic and does not require the use of PPE, therefore your health is not at risk.
SOLUTION: Although spraying Rescue is not a health concern, you can switch to a trigger foamer which will eliminate the aerosolization. Foaming also provides better surface coverage and slows evaporation helping to achieve the required contact time.
