what is the best and most effective way to clean white wall tyres

I had good results with white jif on a chux's cloth

Do a small section at a time , have a bucket i=of water and a sponge handy to wash off , then dry it of and repeat till comes clean

HD wheel and tyre cleaner great stuff

I use ajax,scourer,bikelift and scrub like buggary....prick of a job as the venoms are ridged where the metzlers are not...prefer the venoms though...cheaper than harley shit... (ajax and scourer that is)....

 best cleaner i found was a clean rag and some kero. Takes about 2min each wheel, need to use a new rag for each wheel depending on the size of the WW.
