Your batik can keep its vibrant colours for many years but it is important to follow some suggestions about the correct care:

Avoid washing: Batik paintings are not meant to be washed, as water and detergents can cause damage. Never use sprays, solvents, or cleaning products on the fabric itself or on the frame.

Dust gently: Use a soft, dry cloth or a feather duster to remove surface dust, for framed pieces behind glass, clean the glass only. 

Keep away from direct sunlight: UV rays can fade the vibrant dyes over time. 

Avoid humidity and damp areas: Moisture can cause mold or degrade the artwork, ideal humidity is around 40–60%.

Temperature stability: Avoid placing batik near heaters, fireplaces, or air conditioners as sudden temperature changes can cause damages to the batik or the frame.

Framing and Display: Glass or acrylic frames can give better protection to the surface from dust, moisture, and accidental contact. 

Store flat or rolled loosely: If not framed, roll the batik with acid-free tissue paper, never fold it — creases can break the dye lines. 

Do not iron directly: If needed, place a cloth or oven paper under and over the batik and use low heat when ironing.
