Cleaning a table tennis blade

hi guys.

I need your experience and advice to know how i can clean my blade, yes, only the blade
cause i bought my for three o four months ago, after i testing the same blade from a club partner.

I had this blade since 6ix or seven months, and it still looking good and like new, but my blade looks lika a ancient blade, is dirty, dark, and the grip of the wood is a little sliding, i think the dust and dirt could made this.

how i can clean it?

please helpme

PD: i have a racket case to protect my racket.

Hi Carlos,

You don't need to worry about the blade too much.  If you want you may use a little sand paper but don't sand it down too much as it may effect the balance of the blade.
