How can an airborne treatment get 2" into an upholstery filling?
As Neil says, injection is impractical over a whole carpet but when has anyone/anything peed/vomited on an entire carpet? It's normally used for spot treatment.
I use a syringe to inject solutions into carpet backings and upholstery wadding/cushions. In recent months using this method I've:
- Fixed a horrible tom-cat piddle problem on an armchair
- Saved a west highland terrier from being drowned in a bin liner (after he peed up the corner of a brand new carpet - his owner was furious!)
- Spared an airedale from being banished from the house after he vomited on a very expensive sofa (it soaked through a seat cushion and down into the wadding under the bench)
- Smoothed out a row between friends after one of them fell asleep drunk on the other's sofa after a Saturday night out and wet himself!
I've used different products depending on the problem, but they include several from solutions such as mpower, natural odour neutraliser, freshguard and bio green. I've also used a couple of other sanitisers and deodorisers.
You have to think what's going on where you can't see. You need to counter-act the volume of problem with the right volume of solution. For example, in a sofa cushion that's been vomited on, I'll use a 10cc syringe to inject solution deep into the cushion filling. I've put up to 500ml into a cushion! You just have to tell the customer it's going to be unusable for a couple of days and give it a week until they decide if the problem is fixed.
The only downfall, as with any odour removal job, is you just don't know if you're going to be able to 100% fix it. I'll normally quote to allow one "free" re-visit if the problem still exists, but make it clear that after a re-visit it might be unfixable and further visits will be chargeable.
