I have pressure air & water, the abrasive action cleans the stuck on grime off wheels. Works really well on stubborn dirt. 40psi continuously or 90psi for shorter bursts, could increase to 120psi if needed. 0.5L of water per minute, about 90amps using 3 compressors.

Hmm
This conversation got out of hand due to a spelling mistake !! Watch that auto correct it plays tricks !!
As said use a bucket and soft broom, with a bit of detergent. I just use the hose at home. The bird poo is the worst but comes off OK with a broom. Previously a person said to polish them with car polish to make it easier ! Hmm not worth the effort IMHO.
