i have tried the odor neutralizer gel from CVS and it barely works....supposedly it is similar to ona gel but i dont think it works for shit! i also use febreeze extra strength and it seems to work but not long. i need to spray every couple of hours but i dont because i dont want it affecting my plant. i spray maybe once a week though. still i would like to get something that works all the time. im considering buying ona gel to see if it works any better but i am skeptical now. any ideas will be greatly appreciated!
