According to the Health and Safety Executive, gloves should be worn if:
There is prolonged or frequent contact with water. Look for gloves that meet European Standard EN374-2 – this shows they are waterproof.
The label of the product you’re using indicates gloves should be worn (for example, bottles of cleaning products may show hazard warning symbols). The label or safety sheet may give you information about what type of glove is needed.
Harmful substances are created by work processes.
