Keep your Rains Stainless Steel 2-Pack Cups 300ml looking their best with simple, everyday care. This guide covers hand washing, stain removal, and what to avoid.

Quick Answer

Hand wash your Rains Stainless Steel 2-Pack Cups 300ml with mild soap and a soft sponge to preserve the finish. Avoid abrasive cleaners and steel wool.

Why Hand Washing Is Best

The cups are built for hybrid living—both indoors and outdoors—with a sleek, industrial aesthetic. While many stainless steel items are dishwasher safe, the debossed water-inspired HOME AWAY logo and the smooth matte finish can be dulled by harsh dishwasher detergents and high heat over time.

Hand washing gives you control and keeps the cups looking like new. It also prevents water spots and mineral buildup that can occur in hard-water areas.

What About Dishwasher Safety?

The cups are BPA-free and made from stainless steel, but the manufacturer does not explicitly state they are dishwasher safe. To be safe, stick to hand washing. If you do use a dishwasher, place them on the top rack away from the heating element and use a gentle cycle.

The trade-off is convenience versus longevity. A dishwasher may save time, but it can also lead to etching, discoloration, or loosening of the debossed logo over many cycles.

Step-by-Step Cleaning Guide

1. Rinse Immediately After Use: Rinse the cup with warm water right after drinking coffee, tea, or any beverage. This prevents residue from drying and sticking. A quick rinse now saves scrubbing later. Don't let coffee or tea sit for hours.
2. Wash with Mild Soap and Soft Sponge: Apply a drop of mild dish soap to a soft sponge or cloth. Gently scrub the inside and outside in circular motions. Pay extra attention to the rim and bottom. Never use steel wool, abrasive pads, or harsh scouring powders—they will scratch the surface and dull the finish.
3. Remove Stubborn Stains with Baking Soda Paste: For coffee or tea stains, make a paste of 1 tablespoon baking soda and a few drops of water. Apply to the stained area and gently rub with your fingers or a soft cloth. Rinse thoroughly. Baking soda is mildly abrasive but safe for stainless steel when used gently. Avoid vinegar or lemon juice—they can etch the metal over time.
4. Dry Immediately with a Soft Cloth: After rinsing, dry the cup with a clean, lint-free cloth. This prevents water spots and keeps the matte finish even. Air drying can leave mineral deposits, especially in hard water. A quick hand dry is better.
5. Store with the Lid Off (if applicable): If your cup has a lid, store it separately or leave it slightly ajar to allow airflow. This prevents moisture buildup and odors. Trapped moisture can cause mildew or a musty smell. Always store completely dry.
