How To Clean Tumbled Marble Shower Do I Need To Strip Tumbled Marble Before RESEALING?

Do I need to strip tumbled marble before RESEALING? - how to clean tumbled marble shower

I have a collapsed marble shower is surrounded, that about 5 years. It is beginning to look "white" in some areas. I have all the traditional cleaners and looks great when wet, but will "know" when it dries.

HMK I sealed the stone, but before the seal, it is something Stripping, what I have to? If so, what? Otherwise, agreement by agreement only clean, dry and apply only for 1 or 2 coats of sealer and solve the problem is?

Thanks
