It’s always good to see recommendations for tyre dressings because the products vary so much.
Some last, some don’t, some are messy, some not, some are a bugger to apply, some not.
Tyre fitter’s gunk wipes off with any shampoo or even a bit of washing up water with Fairy Liquid and a kitchen towel if between washes...
Which reminds me, I must get some new Michelins soon
