How to Clean Stroller Shock Absorbers and Springs

Why grit damages suspension components

Shock absorbers and springs are designed to compress and rebound smoothly, absorbing the bumps from uneven sidewalks, trails, and curbs. When fine sand, mud, or tiny stones work their way into the coil gaps, pivot points, or sealed units, the movement becomes abrasive. The grit acts like sandpaper on metal parts, gradually wearing away protective coatings and accelerating corrosion.

The safety standard for strollers, ASTM F833-21, which is incorporated into federal regulations at 16 CFR part 1227, specifically addresses exposed coil springs as a potential hazard. While the standard focuses on pinch points and entrapment risks, it also means manufacturers must design springs with clearances and caps. Dirt and debris can interfere with these protective features, and in extreme cases, cause a spring to bind or fail. Keeping suspension parts free of grit is not just about comfort; it also supports the safe operation of the stroller.

• Sand and silt can settle inside coil springs, reducing their travel and making the ride harsher.
• Mud that dries on pivot points can stiffen the suspension and cause binding.
• Road salt used in winter can accelerate rust on metal springs and shock bodies.

Gather the right tools and supplies

Before you start, assemble a small kit. You will need a soft-bristled brush (an old toothbrush works well), a stiff nylon brush for stubborn dirt, a clean microfiber cloth, mild dish soap, a bucket of warm water, and a small spray bottle. Avoid harsh degreasers, solvents, or pressure washers; these can strip lubrication and force water into sealed bearings.

If your stroller has a suspension system with exposed springs, you may also want a can of silicone-based lubricant or a light machine oil for pivot points after cleaning. Do not use general-purpose oils that attract dust. A dry Teflon lubricant is a good choice for moving parts.

Step-by-step cleaning process

Place the stroller on a flat, stable surface and engage the parking brake to prevent it from rolling. Remove any wheels if they block access to the suspension, but note that some strollers have sealed suspension units that should not be disassembled for cleaning. Refer to the manufacturer's manual if you are unsure.

Start with a dry brush to dislodge loose dirt and sand from the springs, shocks, and surrounding frame. Work in the direction of the coil gaps, and use a toothpick or a wooden skewer to gently pick out packed-in grit. Be careful not to scratch the finish.

Next, mix a small amount of mild dish soap into a bowl of warm water. Dampen a microfiber cloth (not dripping wet) and wipe down the shock body and spring coils. For stubborn areas, use the soapy cloth and a soft brush to scrub gently. Rinse the cloth in clean water and wipe again to remove any soap residue.

Dry all components thoroughly with a clean, dry cloth. Pay extra attention to the small crevices where moisture can hide. Complete drying is essential to prevent rust and to avoid leaving water that could dilute any existing lubricant.

Inspect shocks and springs for wear

While cleaning, take a close look at the condition of your suspension parts. Check for rust, pitting, cracks, or deformation in the spring coils. Inspect the shock body for oil leaks or scoring. Look for loose mounting bolts or worn bushings that attach the suspension to the frame.

The CPSC requires that strollers meet specific performance requirements, including tests for stability and impact, but those tests do not cover long-term wear. If you notice any of these signs, the component may be failing. A worn spring or shock can degrade the stroller's handling and stability, and in rare cases, break during use.

If you see any damage, stop using the stroller until the part is replaced. Our guide on stroller suspension worn out explains how to recognize the warning signs, and how to replace stroller shock absorber covers the replacement process.

Lubrication and rust protection

After cleaning and drying, you can apply a light lubricant to the pivot points and any sliding contact surfaces of the suspension. Springs themselves generally do not need lubrication; they are designed to flex without friction. The goal is to protect the metal from moisture and to keep the mechanism moving smoothly.

Use a silicone-based spray or a dry Teflon lubricant. Apply sparingly and wipe off any excess, as excess will attract dirt. For springs, consider a thin coat of a rust inhibitor such as a light machine oil, but only if the spring shows signs of surface rust. Do not use grease or heavy oil that could trap grit.

If you live in an area with salty winters or near the coast, consider adding a protective layer of automotive wax or a silicone protectant to the metal surfaces of the suspension. This can reduce corrosion from salt and humidity. Our article on protecting stroller frame from rust offers broader advice for winter care.

When to seek professional help

Most suspension cleaning is straightforward, but some situations call for a professional. If you find broken coil springs, a leaking shock absorber, or bushings that are cracked or missing, cleaning alone will not fix the issue. These parts must be replaced to maintain safe operation.

Before replacing any suspension component, check whether the stroller is still under warranty. The registration card that came with your stroller often lists contact information for the manufacturer. If you suspect a manufacturing defect, you can also search reports on SaferProducts.gov to see if others have reported similar failures. To stay informed about recalls, check Recalls.gov periodically.

If you are comfortable with basic tools, you may be able to replace a spring or shock yourself using our guide on how to replace stroller shock absorber. Otherwise, contact the manufacturer or a local stroller repair service. Never operate a stroller with a visibly damaged suspension.

What to pick for your suspension cleaning routine

Questions

How often should I clean stroller shock absorbers and springs?

For everyday strolling in urban environments, a thorough cleaning every few months is enough. If you regularly use your stroller on dirt paths, sandy beaches, or in wet and salty conditions, clean the suspension monthly. Always inspect after a particularly muddy or sandy outing.

Can I use a pressure washer on stroller suspension parts?

No. Pressure washers can force water and dirt into sealed bearings and can damage the finish or rubber bushings. Stick to a brush, a damp cloth, and mild soap. Your suspension components are not designed to withstand high-pressure water.

Should I lubricate the springs themselves?

Usually no. Springs flex and do not need external lubrication. Applying oil or grease to spring coils will only attract more grit. Instead, lubricate the pivot points and sliding contact areas of the suspension linkage, and only if the manufacturer recommends it.

What should I do if I find rust on my stroller's springs?

Light surface rust can be cleaned with a soft brush and a rust remover such as a citric acid solution, then dried and protected with a light oil. If the rust has caused pitting or the spring is cracked, the spring must be replaced. Continue to use the stroller only after the part is sound.

Can I clean suspension parts while the stroller is folded?

It is best to keep the stroller in its unfolded, stable position with the brakes engaged. Folding the stroller may compress the springs and make access difficult, and some parts may move during cleaning, increasing the risk of pinching.
