Bike Wash Concentrate 20L Refill

Some garages wash one bike. Some wash five.

If you're running multiple bikes, kitting out a race team, or just refuse to run out mid-season, the 1L and 5L bottles don't cut it. This is the same Bike Wash you already know, high-foaming, salt-free, safe on aluminium and carbon but scaled up to the point where restocking stops being a chore.

The maths:
Dilute 50/50 and 20L becomes 40L of ready-to-spray cleaner. That's enough for dozens of washes from a single drum, at a lower cost per litre than any smaller size on the shelf.

Still the same formula underneath:

• High-foaming, clings to mud and clay instead of sliding off
• Non-corrosive, safe on paint, plastics, anodised parts, aluminium and carbon fibre
• Biodegradable, no acids or harsh alkaline salts
• Works on bike, kit, boots and helmets alike

How to use it:
Mix 50/50 with water into your sprayer, apply to a pre-rinsed bike, leave for 15 minutes (or 5 with a scrub if you're short on time), then rinse clean.

Whether it's a family with three bikes in the shed or a workshop running through gallons a week, this is the size that keeps you stocked without thinking about it.

How much cleaner does 20L actually make once diluted?
Diluted 50/50 with water, the 20L drum gives you 40L of ready-to-use bike wash.

Is this a better deal than buying the 5L refill?
Yes, the cost per litre drops the bigger you go, so 20L works out cheapest per wash of anything in the range.

Who is this size actually for?
It suits riders with more than one bike, families sharing a garage, workshops, or anyone washing multiple times per week.

Does it perform differently to the smaller bottles once mixed?
No, once diluted to the correct ratio it's identical in strength to the 1L ready to use Bike Wash.

How do I dispense it - does it come with a pump or tap?
The 20L does not come with a tap but we have them available here.

Will it still be gentle on carbon fibre and anodised parts at this size?
Yes — it's the same non-corrosive formula regardless of drum size, safe across paint, plastics, anodised finishes and sensitive metals.
