How to Clean a Smith Ski or Snowboard Helmet
A Smith snow helmet is safety equipment with an impact liner, outer shell, fit system and removable comfort pieces. Harsh solvent or high heat can affect materials even when the helmet still looks normal. Smith recommends a soft cloth or sponge with mild soap and water for the helmet, hand washing removable pads and laying them flat to dry. The helmet should dry in a ventilated place and stay out of attics, garages and car trunks where temperature extremes occur. This guide covers current Smith ski and snowboard helmets, including Mips-equipped models, without separating bonded impact components or soaking fixed liners. Any crash changes the decision: Smith says to replace the helmet after an impact even if damage is not visible.

Step-by-step instructions
Before you begin: Inspect and prepare
Review the helmet's impact history before washing, because cleaning should never erase the decision to retire a crashed helmet. Remove only comfort parts the exact model identifies as removable, photograph their positions and leave Mips layers, bonded foam and fit-system hardware assembled. Resin, fuel, insect repellent, adhesive residue or an unknown solvent exposure calls for Smith guidance even if no discoloration appears. Structural material can be compromised without a stain or crack that an owner can see.
Step 1: Establish impact and age history
Before cleaning, ask whether the helmet took a crash, hard impact or crushing load. Smith says an impacted helmet should be replaced even if it appears fine. Check the manufacture-date label under the liner; active-use age and calendar age also affect replacement planning.
Step 2: Remove only intended comfort parts
Detach ear pads or washable comfort pads only if the model instructions identify them as removable. Photograph their position first. Do not peel bonded foam, separate a Mips layer, remove permanent adhesive or open the fit mechanism.
Step 3: Brush away loose snow and grit
Let packed snow melt at room temperature, then shake out debris. Use a dry soft cloth around vents and the shell. Do not scrape ice with metal or force a brush through vent channels, where it can damage liner surfaces.
Step 4: Prepare mild soapy water
Add a small amount of mild soap to cool or lukewarm water. Smith says to avoid harsh cleaners and solvents. Do not use bleach, acetone, gasoline, adhesive remover, abrasive powder, steam or a strong disinfectant unless Smith approves it for the exact helmet.
Step 5: Wipe the shell and fixed interior gently
Dampen a soft cloth or sponge, squeeze it well and wipe the shell, rim and accessible fixed comfort surfaces. Keep water from pooling inside vents, fit dials or speaker pockets. Use repeated light passes instead of soaking the helmet in a sink.
Step 6: Hand-wash removable pads
Move the pads through mild soapy water and press them gently. Rinse until no foam remains. Do not wring, stretch or machine-wash unless the model label explicitly allows it. Smith says to lay removable pads flat to dry so they keep their shape.
Step 7: Remove residue and air-dry
Wipe the helmet with a clean damp cloth, then towel-blot. Place helmet and pads separately in a shaded well-ventilated room. Do not use direct sun, hair dryer, radiator or clothes dryer. Ventilation also prevents odor between mountain days.
Step 8: Inspect the clean helmet closely
Look for shell cracks, compressed or exposed foam, delamination, damaged straps, a loose buckle or fit system that will not hold. Reinstall fully dry pads in their intended positions. Do not cover a suspicious crack with a sticker or repair safety parts with glue.
Step 9: Store away from temperature extremes
Keep the dry helmet in a ventilated indoor location where it cannot be crushed. Smith specifically warns against attics, garages, car trunks and other areas with large temperature changes. Replace after impact and follow Smith's age guidance rather than assuming a clean helmet lasts indefinitely.
