Sprays

Stub — to be filled out.

Covers aerosol products used on/around bikes. Many sprays are dangerous to specific bike materials — read each label.

Sections to add (TODO)

Penetrating sprays (for stuck/rusted parts)

PB B’laster — best penetrant in tests
Kroil — premium, hard to find in CA
WD-40 Specialist Penetrant (NOT regular WD-40)
Liquid Wrench
Application: spray, wait 15+ min, tap with hammer, repeat
⚠️ Most penetrants contain solvents that attack rubber seals and painted surfaces — wipe off before assembly

Brake / contact cleaners

Chlorinated brake cleaner — strongest, but illegal for non-pro use in some provinces; attacks rubber, plastic, paint
Non-chlorinated brake cleaner — safer, slower
Disc brake-specific cleaner (Finish Line, Muc-Off, Park CB-4) — safe on pads/rotors
⚠️ Regular brake cleaner CONTAMINATES disc brake pads — only use disc-specific products on rotors with pads installed

Silicone sprays

Dry silicone — cable housing, suspension stanchions (clean first), zippers
Wet silicone — squeak elimination, rubber preservation
⚠️ Silicone overspray contaminates disc brake pads — apply far from brakes

Dry / wet chain lubes in aerosol

Convenient for cables and pivots; messy on chains (overspray)
Tri-Flow, WD-40 Bike Dry/Wet, Finish Line Dry

Multi-purpose / displacement sprays

Regular WD-40 — NOT a lube. Water displacer + light penetrant. OK for displacing moisture from cables, terrible as a chain lube
3-IN-ONE — light machine oil with poor staying power; OK for cable ends

Chain wax aerosols

Squirt Chain Wax, Smoove, Silca Synergetic — drip not spray, but mentioned for completeness

Frame protection sprays

Helmet/frame silicone polish (Pedro’s Bike Lust, Finish Line Showroom)
Ceramic spray sealants (after wash)

Penetrating + lubricating combos

WD-40 Specialist with PTFE
CRC 5-56
