Questions about a cleaning product
Tell us which item you are considering and the surface you intend to clean. Include any relevant furniture-care label or manufacturer’s instructions where available.
Please do not assume that a product is suitable for delicate, unfinished, antique, or specially treated furniture unless the listing and furniture-care guidance support that use.
Problems with an order
Describe the issue and include photographs where reasonably available. Images of the product, packaging, or affected component can help us review the situation.
If a product appears damaged, leaking, or unsafe, stop using it and contact us. For a medical emergency or suspected poisoning, seek immediate local medical assistance rather than waiting for customer support.
Return arrangements
Our return warehouse is located in China. Email us before shipping to obtain the full address and relevant handling instructions.
Do not return goods to the business address unless we confirm that it is the correct destination.
