stains at the foot of couches and edge of beds

Try sodium percarbonate.

I add it to my pre-spray and it seems to get rid of them..

If the area is that bad to begin with how are you going to harm it with pre-spray and rinsing it?

the key to sodium percarbonate is that the longer it stays on the carpet the better it works I use it in my prespray as a booster and i go a little heavier on the spots. then i clean the entire room and it work very good. I always carry a gallon of 3% hydrogen peroxide in my van if for any reason I don't have sodium percarbonate I use peroxide instead same thing and cheaper.

yes it does and it does not damage nylon don't use it on cotton or wool I just had a color run on a cotton sofa. peroxide is safer and cheaper

You use peroxide like in the brown bottle from the drug store?

I add two scoops with bad looking areas.

yeap that's the one that's what sodium percarbonate is prety much 3% is the safer to use to my taste nut some times you can use 6% just have to be careful with the mixture it's kinda hard to figure it our but 3% i have use it straight with no problems 6 bucks a gallon compared to more 20 bucks a pound just use it all the time with your pre-spray and see the results 2 or 3 ounces per gallon don't need much

it does my previous answer to jmo explains it all

Peroxide happens to be one of the best cleaners and has been used in hospitals to clean odor less colorless hypoallergenic and is one of the best oxidizers out there. when you see oxi this oxi that think of extremely overpriced hydrogen peroxide. there are some advantages in some product though for example if the product is a combination of surfactants and sodium percarbonate or sodium carbonate you will probably be better off buying that product as you will not need you regular prespray any more you will be substituting and like any other product it has to see with concentrations and quantity of active ingredients.

I would not know that one since you use the hydroforce but I use pump sprayer and I mix only what I need for each job

'cause it lasts only 5 to six hours good thing is if you mixed a l little to much you can empty your sprayer in your garbage disposal to keep it without any bad odors and to destroy build ups inside it

is this the same as 40 sol?

I just moved the couch up a little...problem solved
