Blue Strong is slow in evaporation, allowing it to penetrate deep into pores and remove dirt and oil.

In warm countries it will evaporate faster and sufficient liquid should be used. Unlike Pearl and Solid balls, a Urethane ball does NOT need to be cleaned after playing. Oil keeps the ball soft and that is good for a urethane. If you are going to play a match, throw in the urethane.

When the throw-in stops, only then do you clean the urethane ball. Spray enough Blue Strong on the ball and spread it by hand or with the appropriate small or big pad. With this pad you support the surface to be cleaned. If the liquid is well distributed, wait until it starts to open. As soon as this is clearly visible, the fluid has completed its work optimally. Then wipe the ball dry with a clean cloth.

After this, the ball will absorb the new oil and will retain its effect longer when thrown. The Carbon Fiber and balls that are mixed with other substances can possibly be cleaned after throwing a series, but the Blue Strong is recommended for this. Red Perfect also works on urethane, but will not penetrate as far as Blue Strong, which has been specially developed for these balls and is the strongest cleaner in the world.
