How to Clean a Petzl BOREO Climbing Helmet

The Petzl BOREO combines an ABS shell with EPP and EPS impact liners, polyester webbing and comfort foam. Petzl's helmet instructions limit washing to lukewarm pH-neutral soapy water at no more than 30°C, followed by a thorough fresh-water rinse and air-drying away from UV and heat. Solvents, stain removers and degreasers can weaken polycarbonate, polystyrene or nylon and are not compatible with the helmet system. This guide covers BOREO shell, liner, straps, buckle and removable comfort pieces while preserving the inspection boundary of personal protective equipment. A helmet exposed to a severe impact, aggressive chemical or uncertain damage should be retired and assessed; a clean surface is not proof that its protective structure remains sound.

Step-by-step instructions

Before you begin: Inspect and prepare

Read the individual inspection markings and compare the helmet with its known history before adding water. Remove only Petzl-authorized comfort parts, keep all structural liners in place and photograph strap routing if a removable item is unfamiliar. Paint, marker, adhesive, battery leakage, fuel or insect-repellent contact can be chemically significant even when the shell looks clean. Quarantine the helmet after a major fall, visible deformation, cut webbing, an unreliable buckle or uncertain contamination, and follow Petzl's PPE inspection and retirement criteria.

Step 1: Record history and inspect dry

Check whether the helmet suffered an impact, crushing, extreme heat or chemical contact. Examine shell, EPP/EPS liner, straps, buckle, adjustment parts and headlamp clips. Petzl treats PPE history as part of retirement decisions. If chemical contact is uncertain, retire the product rather than wash and guess.

Step 2: Remove only approved replaceable parts

Follow the BOREO instructions to remove comfort foam or another referenced spare part. Do not separate the impact liners from the shell, pull glued material or dismantle the adjustment system. Photograph strap routing before removing any authorized comfort piece.

Step 3: Prepare the exact mild bath

Use lukewarm water at 30°C/86°F maximum with a small amount of pH-neutral household face or body soap. Petzl excludes solvents, stain removers and degreasers because they can weaken helmet materials. Do not use bleach, strong disinfectant, hot water or a dishwasher.

Step 4: Wash without pressure or abrasion

Use a soft cloth or sponge on the ABS shell, accessible liner surfaces and webbing. Move the chin strap through soapy water gently. Do not use a high-pressure sprayer, stiff brush or abrasive pad. Support the helmet rather than compressing it against the basin.

Step 5: Treat salt exposure promptly

After seaside or other salty use, Petzl says to rinse with fresh water. Work clean water around straps, buckle and headlamp clips where crystals collect. Do not wait for salt to dry repeatedly into textile and metal interfaces.

Step 6: Rinse thoroughly with fresh tap water

Remove all soap from shell, liners, webbing and buckle. Change rinse water until there is no foam or slippery feel. Use gentle flow rather than a pressure nozzle. Soap residue can trap dirt and irritate skin during a long climb.

Step 7: Air-dry away from UV and heat

Blot with a towel and place the helmet in a ventilated shaded location. Petzl says to air-dry away from UV, direct sun, fires and radiators. Do not sit on, compress, tumble-dry or leave the helmet in a hot vehicle, where temperature can exceed safe storage conditions.

Step 8: Reassemble and inspect again

Reinstall fully dry comfort foam and approved spares exactly as intended. Confirm the buckle closes, straps run flat, adjustment holds and liner remains seated. Do not paint the shell or hide cracks with stickers not supplied or authorized by Petzl.

Step 9: Store protected and ventilated

Place the dry BOREO in a pack or dedicated space where crampon points and sharp tools cannot reach it. Keep it away from sunlight, damp waterproof containers, fuel, batteries and cleaners. Do not throw it on the ground or store it under heavy equipment.

Specific cleaning questions

Open a question for a concise answer about stains, odors, safety, frequency, and troubleshooting.

What soap can I use on a Petzl BOREO?
Petzl specifies pH-neutral household face or body soap in lukewarm water.
What is the maximum wash temperature?
Keep the water at or below 30°C/86°F. Check the prepared water before immersing any helmet parts.
Can I use degreaser or stain remover?
No. Petzl warns that these products can weaken helmet plastics, foam or nylon.
Can I pressure-wash the helmet?
No. Petzl explicitly says not to use a high-pressure water sprayer.
How do I clean salt from the helmet?
Rinse it thoroughly with fresh water after use in a salty environment.
Can I dry it in direct sun?
No. Air-dry away from UV and heat sources such as sunlight, fires and radiators.
Can I paint or sticker the shell?
Do not paint safety parts. Use only markings and stickers allowed by the exact Petzl instructions.
What if the helmet contacted an unknown chemical?
Petzl advises retirement when chemical compatibility is in doubt; cleaning cannot verify hidden strength. Record the substance if known, isolate the helmet from shared gear and consult Petzl rather than attempting another solvent or neutralizer.
