Pineapple Express is Crankalicious's rapid acting spray wash, and this is the 250ml concentrate refill rather than a ready mixed bottle. Diluted with water at 1 to 3, or made up as 250ml of concentrate topped up to a litre in a spray bottle, it covers the frame, brakes and contact points of the bike. Spray it on, let it dwell for 2 to 3 minutes, then agitate with a brush, mitt or clean cloth before rinsing thoroughly with a low pressure spray. The concentrate format suits riders who already own a spray bottle and want a more economical refill, and it pairs naturally with a microfibre drying towel and a dedicated chain cleaner for a full bike wash.
