RE: Carbon Blast?
If you look closely in those " No black mess" adds they show that they are using the same amount of each....The guy is soaking wet!!! You don' t NEED that much! Usuing the proper amount, there is very little " mess" . And as mentioned, you can spray the INDISE of your clothes.
Once sprayed on...it absorbs into your clothing...so the black dissipates quickly.
Not sure if I believe that it works 18-20 TIMES better than other scent killers (you could use 20 times less?) but I do think that if you are REALLY worried about scent...the carbon blast will work best.
