The use of the spray that contains alcohol (denatured) is permissible and does not make the clothes najas (impure), hence, one can make Salaah. The type of alcohol that is used in the spray is not that is used in the beverages and the like.

I was wondering why synthetic alcohol is permissable and came across this:

"Cetyl alcohol is a long chain alcohol which is solid hence obviously not drinkabale nor does it cause intoxication if at all ingested. Therefore, it is halal to use in cosmetic products. It is also not absorbed through the skin when applied as a cream.

However, Synthetic Ethyl Alcohol, which is a short chain alcohol (C2H5OH) and is a liquid, is not halal. Because it causes intoxication when ingested. As the Ulema say anything that causes intoxication even in a very small quantity will therefore be haram.

Fruits such as dates and grapes when they are putrified, produce Ethyl Alcohol which is the intoxicating agent and that is why it makes Khamr a haram drink. "
