Just bough a new alko (pheumatic tyre) to replace the existing rubber one. Noticed the handle is not as long a hence seems much harder and more effort to turn. Also it appears to be dry, can I , should I lubricate, if so what with...the van appears to have a lot of white looking grease on a lot of the parts after the service? I guess normal grease is going to be mucky and a potential hazzard for getting on clothes etc...or am I just being Mr fussy!
