Red Perfect is specially developed for the Solid – Solid Reactive – ball and evaporates more slowly than the Yellow Strike, because the ball has an open structure. The Red Perfect therefore needs more time to draw the dirt and oils out of the ball. Evaporation also depends on humidity, so will be faster in warmer countries than in colder countries.  Red Perfect is also recommended if the Solid Reactive ball consists partly of < less than 50% urethane. Make sure that enough of your liquid is sprayed over the ball and distribute it well by hand or the supporting polishing pad small/big. Once the liquid is well distributed, wait until you see that the liquid opens up. When you see this, remove the liquid-dirt etc.-from the ball with a clean cloth. Use a clean cloth for this, as we often see balls being “cleaned” with a dirty cloth and oils/dirt being reapplied coming from the dirty cloth on the ball. After cleaning, store the ball back in your bag.   Clean the ball after every round of play; it takes a few minutes to get used to it, thus keeping your playing equipment in good condition.   Note: If a Solid – Solid Reactive – ball is polished afterwards, the recommendation remains to use Red Perfect use. Blue Strong can also be used on a Solid – Solid Reactive – ball, but is more expensive to buy, Red Perfect therefore deserves the recommendation.
