Although it helps to give the impression of cleaner fresher carpets, I wonder how long the benefits of odour products last.
If you put it in the tank a certain amount must be absorbed into the carpet Fibres , but then you suck it out again.
If you spray it on trigger spray you only use say 500ml mixed max.
The other question is how sticky is this stuff.
I'm using the Chemspec one at present Citrus Its called odour ................
Prior to that Prochem, I buy according to where I am when I need supplies
I did a smoke filled betting shop certainly killed the odour, but when I went back the next day, the smokers had been in and although not so strong the cig smell was back.
Perhaps I should sell them a twice daily boast.
