Cleaning the tyres
Having a clean tyre will get the absolute best out of Sweet Rubber & Tyre Sheen, and help with application, and longevity.
Spray some Down & Dirty straight onto the tyre and leave it to dwell for a short time, but don't let it dry. Then, with a stiff bristled brush like our Little Stiffy, scrub the tyre thoroughly with a mix of car wash like Dirty Times or Nanolicious Wash and then rinse off all of the excess suds. Dry the tyre with a Dirty Deeds or Twisted Little Sucker cloth and inspect - if it needs more cleaning, repeat the process until the rubber looks bare, ready for some tyre shine application.
If the tyres have significant browning from antiozonant (an additive put into all new tyres to help keep the rubber supple), they may need more than one application to remove all of the brown staining from the rubber. Tyre Sheen and Sweet Rubber both contain additives to help keep the rubber of the tyre supple, so don't stress if you're removing it.
