In our rug cleaning arsenal are the following items that you can find just about anywhere:
- White vinegar
- Water
- Paper towels
- A spray bottle
Yeah all we use is diluted vinegar. We use a one to one ratio of vinegar to water. Just fill the spray bottle up half way with water, then top it off with vinegar. Mix well. This is what the folks who cleaned my parents carpets recommended. We found out the hard way that commercially available products leave this nasty residue that actually makes more dirt stick to it. This sort of defeats the whole purpose of cleaning the rug in my opinion. The vinegar has the added benefit of covering any residual smells. One reason pets pee on rugs is they smell the urine from an earlier accident or another animal. In their brains this means it is a prime bladder emptying station.
I've found that newspaper soaks up any extra liquid- and dries the rug a lot quicker and saves you from using so many paper towels. I would be careful if you have a light coloured rug- but it works for my dark carpets.
Vinegar doesn't always remove red stains on my carpet. Probably because I have thick, shaggy carpet. I used a wet towel and an iron for those stains. I have light carpeting. I don't know how the iron method would affect dark carpeting.
