What Not to Mix When Cleaning

Do not mix cleaning products. A product that is appropriate on its own can become unsafe when combined with another product.

The simplest safe routine is one product, one label, one task at a time.

Quick plan

1. Read the full label before opening the product.
2. Use one product at a time.
3. Rinse only when the label directs.
4. Ventilate as directed.
5. Stop and leave the area if you notice irritation or an unexpected odor.

Never combine products

Do not combine products in a bottle, bucket, sink, drain, toilet, disposal, or on a surface.

• Do not assume two household products are compatible.
• Do not add a second product to improve results.
• Do not reuse an unlabeled container.

Avoid back-to-back use

Residue from a first product may remain even when the surface looks dry.

• Follow the label for rinsing and drying.
• Do not immediately apply another product.
• When unsure, stop and contact the manufacturer.

Keep original labels and containers

The original container provides directions, restrictions, and emergency information.

• Keep labels readable.
• Do not transfer products to drink or food containers.
• Close caps and triggers after use.

If something goes wrong

Leave the area and follow the product label or local emergency guidance.

• Move to fresh air if it is safe to do so.
• Do not try to neutralize a mixture with another product.
• Keep the product labels available when seeking help.

Safety note

Follow label instructions. Test on a small area first. Do not mix cleaning products.
