Cleaning & Maintenance:

• Routine cleaning: Clean regularly with warm water, mild liquid detergent and a soft cloth or non-abrasive sponge.
• Rinse and dry: Remove detergent residue and dry the surface to minimise water marks and mineral build-up.
• Avoid abrasive products: Do not use abrasive powders, cream cleaners, scouring pads or chemically aggressive detergents.
• Treat everyday stains promptly: Use very hot water and a suitable cleaning product, then rinse thoroughly.
• Treat stubborn organic stains carefully: If required, fill the bowl with a highly diluted organic cleaner such as bleach overnight, then rinse with warm water and wipe with a soft cloth.
• Protect from heat and impact: Use a protector beneath hot cookware and avoid dropping heavy or sharp objects into the bowl.
• Accessory care: Wash removable boards, colanders, mats and covers separately according to their materials and dry before storage.
• Maintain wastes and overflow: Remove debris from basket wastes and periodically flush the overflow path where fitted.

Extra Information:

The ST-BL1590U is built for customers who want maximum single-bowl capacity without an exposed topmount rim. Its 55-litre bowl comfortably handles oven trays, large platters and bulky cookware, while undermount installation keeps the surrounding surface uninterrupted.

The deep black moulded-granite finish creates a bold visual anchor and helps soften washing noise. Overflow availability depends on the selected variant, so waste and overflow details must be confirmed against the exact SKU before fabrication.
