Troubleshooting Carpet Cleaner

No one goes out of their way to make cleaning their carpet more challenging, and nobody wants their flooring to look worse after a shampoo. However, incorrectly using carpet cleaner or failing to evacuate as much moisture as possible is a problem.

Understand the nature of your carpet before you attempt to clean it on your own. Or, hire a professional cleaning service to reduce the chance of foaming and other issues. Too much foam and moisture can lock in odors and stains.

The type of fibers used for a carpet, the pile, and other factors will influence what type of approach is best for cleaning your carpet. It may take longer to clean a natural wool rug compared to a synthetic fiber rug with a shorter pile.

Be cautious about the type of cleaning agents that you use and the amount applied to your flooring. Also, make sure to follow the manufacturer's instructions when using a carpet cleaner and solutions.

Why Is My Carpet Cleaner Foaming?

It isn't necessarily a bad thing if a carpet cleaner is foaming. It's important to note that a carpet cleaning agent may be foaming to improve the effectiveness of lifting out dirt, stains, and grime from carpet fibers.  However, too much foam can be problematic.

A cleaner may foam a bit when using a carpet cleaner or shampooer. Using too much cleaner can cause excess foaming. Any residue left behind from past carpet shampooing can also cause excess foam when cleaning your carpet again.

You may actually discover more dirt left behind on your carpet if you mix your cleaning solution too strongly. Excess foam may be difficult to remove, especially if you work too quickly and have too much on the floor.

Avoid getting the rug pad underneath carpet too wet with any foaming cleaner or shampoo. If you do, it may take a very long time to gradually lift it up and out. Excess moisture will trap dirt, smells, and may cause mildew and mold.

Some Carpet Cleaning Tips

Take your time when cleaning carpet and don't rush the job. Make sure to run over the carpet, removing as much carpet cleaner, dirt, and moisture as possible. The water should eventually be clear, a sign that you are done cleaning.

Don't use too much cleaner, fail to follow suggested instructions on products, or leave cleaner or water behind in the carpet. Persistent problems with mold, mildew, lingering stains, or foul odors may require a professional cleaning service.

Avoid shampooing your carpet too frequently, leaving water behind in the fibers or pad underneath, and not giving your carpet enough time to dry. Use fans and open windows to help your carpet fully dry after cleaning.

Allow your carpet to dry completely before replacing furniture or resuming use of the space. Also, consider toxic ingredients in spray foams and how long they may linger. You may want to steam clean carpets or use alternatives.

Before You Start To Clean

Before you start, know the best way to clean your carpeted flooring. Different carpet fibers and types will react differently to cleaners and methods. Also, review the ingredients used in carpet cleaners for potential hazards.

If there is any foam or residue from a cleaning solution left behind in the carpet, it could linger for weeks. Consider your cleaning options for your carpet and whether hot water extraction, dry foam, or other alternatives will reduce foam.

Where Does The Defoamer Go In A Carpet Cleaner?

To clean your carpet, dirty water, cleaner, and dirt is drawn into a tank.  If you have too much foam, you will want to add a defoamer to your extractor recovery tank. While running the cleaner, the defoamer breaks down any foam.

You can also add defoamer to the end of any extractor hose so it gets sucked up into the machine. If you wish, you can try using a homemade defoaming solution versus a commercial product. However, do a test run to prevent any issues.

Consider adding 1/4 cup of white vinegar to your tank along with a bit of baking soda. Or, you can try adding a little fabric softener, salt, or even dish detergent to a tank of water to break up foam. Do not add defoamer directly to the carpet.

Avoid rushing; take your time when cleaning your carpet, allowing the defoamer to work. If your defoamer isn't working, try drying out your carpet and find another way to remove any excess foam or dirt left behind after cleaning.

What Happens If You Use Too Much Carpet Cleaner?

If you manage to use too much cleaner than suggested for your floors, you may end up with more dirt. Dirty water combined with excess carpet cleaner will attract more dirt, leave more dirt behind, and cause poor removal.

When you think you are finished cleaning your carpet, run your machine over the carpet with a tank of clean water alone. Resist the urge to add more cleaner, and take your time going over the carpet to suck up what you can.

Try to only clean your carpet when needed and give it plenty of time to dry and go without another shampoo for a while. Over shampooing your carpet can leave behind excess moisture and cleaner residue.

You can remove excess carpet cleaner in your carpet. Clean out the tank and add 1/4 cup of white vinegar to fresh, clean water. Run your cleaner over the carpet once more. Or, consider steam cleaning or hiring a professional service.

Why Does The Carpet Bubble After Cleaning?

It may be tempting to use hot water to clean and rinse your carpet, but hot water could be causing bubbling. Help reduce bubbling in your carpet by running over it slowly when cleaning, and use cool water on the rinse cycle.

When hot water is used on a carpet, if there is latex underneath the flooring, it will stretch as it heats up. Spaces will be created between the backing of the carpet and the fibers, leading to bubbles, buckling, or a ripple effect in places.

Give your carpet enough time to fully dry and eventually any strange, visible anomalies in your carpet will dissipate. Additionally, if you still see ripples or bubbles in your carpet, chances are it isn't fully dry. Wet carpet likes to bubble.

Once enough moisture leaves, the carpet will return to its normal shape. Help things along and open up windows, run fans in front of your carpet, and promote good air circulation. Don't rush when cleaning or resuming use of your floors.
