On your suggestion, I bought the sprayer from Home Depot. It did not work well for me. It had good pressure when I cracked it open but the stream quickly went limp.
Sounds like you are using a small diameter hose, or a really long one. If it was the water pressure, it would be low even when you just cracked the sprayer on. Glad you got another sprayer to work though.
for really tough stains Ive used the Wearever brand brakleen sprayed on a rag and it lifts everything. I have a friend that rents linens for banquets and thats what they use to get stains out of the tablecloths.
Today I rescued my tortured and heavily stained carpet from the scrap heap!
This is how bad it was:
I used my spot-bot with resolve cleaner to work on the stained spot. This is about the best I could get it.
Then, I sprayed almost an entire bottle of resolve on the whole carpet. I scrubbed the resolve into the carpet with a brush, then used a pressure washer with the jet set to a narrow fan pattern. I washed the resolve out using a sweeping motion from the center, outward. After a while there was no more white foam.
Unfortunately, the bad oil stain hadn't been effected much since the initial treatment. It kept a brown color. But, I found something that worked very very well: Carb cleaner. Sprayed some on, scrubbed it in, and blotted it out with a paper towel, (wearing gloves!) This cleaned the last bit of the stain out. Final result?
I'm still in disbelief that it cleaned up so well.
I did this and I used a mild muriatic acid mix, 4 to 1 , that Is 4 water 1 acid, it removed any and all rust stains, and Dawn liquid soap, it looks like brand new and don't forget to use the brush and rinse well, my trunk liner was terrible and I can't believe how good it looks.
Thanks for posting this thread. I literally just had to clean my trunk carpet as well after reading this tutorial. I used different cleaners but the end results were comparable to yours. I used "spray nine" and applied that directly to the heaviest stains. I then used a medium stiffness brush and scrubbed the stains. This worked very well for my carpet. After that, I immediately used a spot and stain remover by Bissell. After scrubbing that on the entire carpet, I then hosed it all off with the garden hose. Here are the results. And yes, this is the same carpet. I'm not sure why the colours look different though.
