For the foam seating I'd use a syringe to deliver the product into the foam.
Then place the cushion or seat if possible inside a compactor sack/plastic bag and place your vac hose on. Close the bag around the cuff and let it suck all the air out of the foam. As it does this it pulls the deodoriser out to the walls of the bag treating the foam from the inside out.
The only challenge can be the legs on the chair if they can be removed. I put holes in the bag pop the legs through then duck tape them so it will seal.
Can someone elaborate on how long the cushions would need to stay in the bags for... & also whilst were here... how long "Really" should these kind of products be in contact with the fabric & foam & inside the underneath wood etc etc for them to truly work their magic
& when it comes to cleaning this type of contamination lets say for this armchair... how would you price up this kind of work involved here?
I mean... lets just say that your usual price for cleaning an armchair with general soilage is £40... how much would it be to clean the same chair with urine contamination?
Im not asking anybody to give me their exact price (unless they want to)...
More just some kind of rule of thumb when it comes to pricing these kind of jobs
