Sons Scott MTB - Spring clean

Puncture repair n clean for my sons bike as well yesterday in the vain hope he may switch back from road riding, occasionally for a ride with me. If that won't do it, not sure what will! Approx 7 year old basic Scott, 27.5, Single Suss - sound . Great buy in a sale at Rutland.

No time/ energy left to clean my MTB. The only one regularly ridden currently
