As a CPST, over the years I’ve had more than a few parents contact me with a tale of bodily function woe. Their potty training children have had unspeakable accidents. A bout of car sickness left the seat looking like a sea of cottage cheese. In one memorable case, a skunk sprayed the seat. (And in case you’re wondering, if a skunk sprays the seat, you’re pretty much out of luck.)
As a parent myself, I know the feeling. You’re driving along, and hear the unmistakable ‘urp’ from the back seat. You white knuckle it until you find a safe place to pull over, but, too late, and you are left with a terrible, awful, no good, very bad mess to clean up.
The question you are left with is, ‘how do I clean this thing?’. Some parents jump in with both hands and a bottle of bleach. At the end, they are left with an entirely clean, and entirely unusable seat. Other parents mistakenly believe that the car seat is a delicate flower that cannot tolerate any sort of cleaning at all. They anxiously wonder if they should simply replace the seat for a minor spill of a cup of water.
As always, your number one resource is your child restraint’s manual. Every manual will have instructions on cleaning the seat, and do’s, and don’ts.
Here at CSFTL, we want to give you some basic, general tips for cleaning and decontaminating the harness of your restraint. As always, defer to your manual. If there is a conflict between this article and your manual or manufacturer’s instructions, defer to your specific seat.
1. Speed is your friend: The quicker you start working, the better chance you have of salvaging your child’s seat. It might be tempting to stick that seat on the porch until tomorrow, but it’s not worth the risk, especially if you can’t afford to replace the seat. Assemble what you need in advance: the seat, a bowl of fresh tap water, a bottle of gentle soap, baby wipes, and clean rags.
2. Remove gross matter: Use a baby wipe, and pick off any substance that is removable without rubbing, scrubbing, or using a cleaning solution.
3. Wipe down the harness: Using a soft cloth and cool water, wipe off the harness. If water isn’t going to cut it, use a gentle soap. “GENTLE” AND “NATURAL” ARE NOT THE SAME THING. (see below)
4. Cleaning the buckle: Invert the buckle in a cup of tap water, keeping the webbing out of the water. Swishing it around will dislodge anything trapped in the mechanism.
5. Sun and fresh air can help: If the harness is removable, lay it flat in the sunshine for a few hours. Any remaining odor is likely to dissipate.
6. Rinse and repeat: If you’ve followed these steps and your harness still has an odor or significant staining, try, try again. In some cases, the harness is replaceable for a small fee from the company. If you still have staining or odor, consider calling your manufacturer to ask if you can purchase a new harness for your existing seat.
It can be comforting to realize that manufacturers understand that children are, well, wet. They leak unmentionable fluids from impolite orifices. They spill things. They have accidents. Car seats can be intended to last a child many years. A harness that melts like sugar the first close encounter it has with a sippy of apple juice would not be a practical design for a product intended for children.
However, while the harness is hardy and durable, there are certain DO NOTS that you must keep in mind when cleaning your child’s restraint.
1. DO NOT: ever, ever, ever place your child’s harness in the washing machine. Sure, it seems like a practical idea, and it’ll come out sparkly clean, no doubt.
So, why can’t you do this? The answer lies in the tensile strength of the webbing. Car accidents hurt people because, among other things, of the short amount of time between traveling at whatever speed you may be traveling, and coming to a full stop. Restraints serve the purpose of slightly elongating that period of time (Called ‘ride-down time’). The webbing (material out of which the straps are made), specifically, will stretch, in a crash, reducing the amount of force transmitted to the body of the child. Spinning those harness straps around in the washing machine will prematurely pull all the stretch right out of the harness and take away that increased ride down protection they provide your child.
2. DO NOT: use abrasives to clean your harness. No matter how tempting, please don’t go at the harness with steel wool. You’ll chew up those delicate fibers, and while an individual broken fiber may not mean much, a whole bunch of them will eventually weaken the restraining capacity of the harness.
3. DO NOT: use harsh soaps. If soap is permitted by the manufacturer in cleaning the restraint, always choose a gentle soap. GENTLE AND NATURAL ARE NOT THE SAME THING.
I’ve had parents earnestly tell me, “Well, I live naturally, and I clean everything I own with vinegar. How could vinegar possibly hurt a car seat? It’s all-natural!”
While as an aside, I would like to point out that many things are natural, like poison ivy and small pox, but not necessarily desirable, the primary point is that natural does not necessarily mean gentle. Vinegar, specifically, is an acid, and a rather strong one.
The pH scale measures the concentration of hydrogen ions in solution. A neutral pH is 7.0, and what you would expect your drinking water to measure, if you were so inclined. (Human blood is around 7.35-7.45). Common household vinegar runs around 2.3-3.0 pH depending on which of the numerous available articles on vinegar available on the internet you consult. In comparison, hydrochloric acid (dependent on molarity and other things, of course), runs around 1.0). Lemon juice is a 2.0.
On the other end of the scale (>7.0-14), we have what are known as ‘bases’. A well-known example of a base is household bleach, which has a pH of 12.6. Another common household cleaner, Borax, has a pH of 9.3. And the most common household base, which we all know as a quick pinch solution for a bad case of indigestion, is baking soda, with a pH of 8.3.
It’s important to remember that the pH scale is logarithmic, so these differences in numbers are not small potatoes. The difference between 7.0 and 2.0 is not ‘5’ but 10 to the fifth power.
So why is a cleaning solution with a pH not near neutral bad for a car seat harness? Acids are corrosive and bases are caustic. Remember the example of steel wool up above, which uses friction to break down the integrity of the car seat webbing? Corrosives and caustics do the exact same thing, but on a chemical rather than mechanical level.
So what ARE gentle soaps? Anything with a pH near neutral is probably gentle enough to use safely on a car seat harness. While we can’t recommend a specific brand, some examples of commonly available gentle soaps include Dawn Dish Soap (7.4 pH), Johnson & Johnson’s Baby Wash (6.5-7.0) and Dove bar soap (7.0).
What kinds of information can you expect to see in a manual?
The above images were selected from the manuals of different seats manufactured by the companies in question, or from the FAQs section of their websites. Some companies provide no specific information about cleaning in the manual, or only address cleaning the seat pad but fail to give specific instructions for cleaning the harness. In those cases, it’s best to call the provided customer service number and speak with a customer service representative for further assistance.
Bottom line though? Avoid this, and you’ll likely be in good shape.
Wishing you clean thoughts!
