Know Your Stain

Knowing what you’re dealing with is the first step to successful stain removal.

There are three main types of stains, which are made up of various chemical compositions and can vary in color:

1. Water-Based

Water-based stains usually stem from liquids such as beverages and food. Such stains aren’t the toughest to get rid of, depending on the drink.

Remove these stains using a water-based solution. If you need something more potent, a carbonized or oxidized solution will help to break up the area.

Carbonized cleaners are most often used to remove grease stains from cooktops and grills, rather than stains from carpets. However, they’re still highly effective on carpets.

2. Oil-Based

Oil-based stains can be hard to remove from carpets; you also have to be careful how you handle them.

To remove oil stains, a water-soluble cleaner works best. These can be alkaline cleaners, and even baking soda is effective at removing this type of stain.

However, before applying any product, blot the stain out as much as possible, but without rubbing the blemish in.

3. Organic-Based

You might need a bucket for this bit…

Organic-based stains are things like vomit, blood, and urine. These types of spots might be more common in households with pets or families with young children.

In order to remove these stains effectively, you’ll have to introduce some good bacteria. Enzyme-based or enzymatic cleaners are a good option here (1).

Finding the Best Carpet Stain Remover

One cleaner might be the perfect solution for your neighbor, but it might not work for you. There are many reasons for this. Examples include carpet weave, stain type, the source of the stain, the carpet’s age and many other factors.

Here are a few things you should understand before you choose a carpet stain remover.

Types of Stain Removers

Professional Cleaners

Some stain removers are labeled “professional strength.” These are highly potent and contain harsh chemicals. However, some stain removers are reserved for professional use only. These must be handled with care and only used in ventilated rooms.

Nothing stops you from using one of these, but you need to know how to use them. If in doubt, consider one of the other types below.


Oxygen-based cleaners become activated when exposed to the stain and oxygen. They’re excellent for colored stains.

The oxygen creates a reaction that breaks down the color molecules. That reaction between the cleaner and the stain will continue as long as there are molecules and oxygen.

Examples of stains best suited for this cleaner are red wine containing artificial color and pet vomit (if the food contained colorings).

Enzyme Cleaners

Enzyme cleaners consist of live enzymes (bacteria), which feed off of organic matter found in the stain. This could be any organic-based stain, as we mentioned above.

The enzymes will keep feeding until the stain is gone and will slowly die, as they don’t have any more food.

Clear Directions

When dealing with carpet stains, you must follow the directions. Using the wrong cleaner, or doing it the wrong way, could ruin your rug or carpet.

Some stain removers require you to do some work on the stain beforehand. This might include blotting out the stain if it’s wet.

After working on the stain, directions usually vary between products. You might be directed to leave the solution to soak for up to an hour. Others should be removed within a few minutes. Products with a short reaction time tend to be stronger. If the chemicals are left for too long on the carpet, they’ll cause damage.

If, after your first attempt, you don’t reach the desired results, you can give it another round, repeating as needed and as stipulated by the directions. You might find one that can be repeated immediately, while others require hours or even days between treatments.

Note though that products requiring a longer reaction time might not be the best for families with young children. You should keep clear of the area to avoid exposure — strong odors might also be present.

How you work the stain may also vary from product to product. Some will instruct you to start from the edges of the blemish and work your way in. Others require you to agitate the solution into the stain.

It’s also important to look at how the cleaner is removed once finished. Some require rinsing, while others don’t. You might find solutions that require vacuuming, although this isn’t as common.

Drying Time

Odors and chemical evaporations are typically destroyed during the drying time. So most labels will caution you to keep the area clear during this time.

We also recommend that you consider the location of the carpet before choosing a product.

If it’s in the living room where there’s lots of activity, a long drying product won’t be suitable. Here, you should go for a product that can be applied, treated and removed within minutes.

You can hurry the drying process in several ways. For example, using a dehumidifier in the room will help keep moisture at a minimum. Using a fan or air conditioning unit to give a better air circulation will also help.

Odors and Residue

Stain Remover Odors

Stains can often be followed by an unpleasant odor that also needs to be treated.

Fragrances like citrus are often used in cleaners due to its effectiveness in covering up other odors. This is only a good option if you like the smell of citrus. Be careful if you have pets, though, as cats, especially, dislike the smell of citrus!

Products labeled as “safe around children and pets,” can still have a pungent odor. Natural stain removers might also have a smell that resembles chemicals.

So when choosing a product, we suggest you read customer reviews to see how they found the odor. Overall, in most situations, it is best to choose a product labeled as “low odor.”

Combatting Residue

Spending the time and effort to remove a stain on your carpet only to find residue can be frustrating. Some products might leave a sticky film that attracts dirt and dust, making the carpet look dirty.

Others dry sticky if not rinsed. This can cause the threads of the carpet to stick together.

As with any product for carpet, do a spot test somewhere inconspicuous. Then check for a residue afterward.

Spot Test Tip

If you do a spot test, make sure you allow the area to dry completely before determining whether the product is suitable.

Because it’s a concentrate, you have to dilute it with water. But, don’t worry, the manufacturer gives full instructions on how to dilute it to suit the task.

Why We Love It


Living in a house that is prone to stains, you may find yourself with multiple cleaners for each task. However, this 5-gallon jug-of-wonder can be used around the whole house.

The brand recommends that you mix a portion of the concentrate with water in a spray bottle, which will make the application easier. It also doesn’t require soaking for long, but you do have to rinse it off.

Low in VOCs

Despite being a concentrate, Genesis 950 is low in volatile organic compounds (VOCs). These are usually found in cleaning products, are terrible for the environment, and can also contaminate the air you breathe.

Genesis 950 contains only regulated toxins, to abide by the standards set by State and Federal regulations.

Excellent for Pet Mess

The product uses oxygen to target the stains and remove them quickly. It cleans deep into the carpet so you won’t have to deal with restaining.

How to Fix Restaining

A stain will often seem to be gone forever, only to reappear when the area is dry. This typically happens if the stain went all the way through the carpet and into the backing. Every-day tasks like vacuuming could bring such stains back.

Vacuuming or activity in the area will make the fibers move, gradually causing the stain to rise. Unfortunately, the only thing to do is to treat the area again.

It doesn’t mean your stain remover is insufficient, though. Often, the deeper the stain is, the more solution is required. So, check the instructions as to the amount to use; if there’s no guideline, use as much as possible.

The Reality of Stain Removal

When you buy a product to remove the stain from your carpet, you, of course, want it to work straight away. However, this is not always the case. No matter how potent the formula is, if the stain is tough, it might require a second round.

It’s essential to keep this in mind: even the best carpet stain remover might struggle with certain spots. A good product, however, will work fast and dry without a residue or chemical odor.
