What to Use in Dishwasher: A Practical Guide for 2026
Learn what to use in dishwasher for spotless results, including detergents, rinse aids, salt, and loading tips. Practical guidance for hard water and eco-friendly options.
In this guide you’ll learn exactly what to use in your dishwasher to get spotless dishes: choose the right detergent (tablet, powder, or gel), add rinse aid for drying and spot prevention, and use salt only if your model has a water-softening feature. Follow your machine’s manual and start with the basics described here.
What to put in dishwasher: detergents, salt, and rinse aids
Your dishwasher runs on a careful balance of cleaning agents and hardware. The core inputs are the detergent, a rinse aid, and, if your unit uses it, salt for water softening. Detergent is the cleaning agent that breaks down food soils. Rinse aid helps water sheet off surfaces for better drying and fewer spots. Salt softens hard water by regenerating the machine’s built-in water-softening system. According to Dishwasher Tips, understanding your water hardness and your machine’s design is the first step to selecting the right inputs. Check your user manual for suggested products and fill ports, but the general guidance here will apply to most modern machines.
- Detergent: tablets, powders, or gels are designed to release cleaning agents under heat and pressure. Tablets are convenient and dose consistently; powders offer load-size flexibility but may leave residue if not fully dissolved; gels are helpful for targeted cleaning or pre-washes.
- Rinse aid: a liquid additive that reduces surface tension, helping water sheet off and aiding faster, cleaner drying. In hard water areas, keeping rinse aid at an appropriate level can dramatically reduce spotting.
- Salt: if your dishwasher has a water-softening reservoir, you’ll need to replenish salt periodically. This reduces mineral scale and helps detergents work more effectively. Always confirm with your model’s specs to know if salt is required for your water conditions.

The following blocks expand on the core inputs to help you tailor usage to your home:
- How detergents differ by format and load type
- When to use rinse aid and salt
- How to avoid common dosing mistakes
Tools & Materials
- Dishwasher detergent (tablet, powder, or gel)(Choose based on your machine’s guidance and typical loads.)
- Rinse aid(Use if your dishes show spots or you want faster drying.)
- Water-softening salt (if your machine uses a salt reservoir)(Only needed for hard water regions and if your model requires it.)
- Dishwasher-safe cleaner (optional)(Use periodically to clean the interior and filters.)
Steps
Estimated time: 25-45 minutes
- 1
Identify detergent options and match to your machine
Consult your dishwasher’s manual to see which detergent forms are recommended (tablet, powder, or gel). Choose a format that aligns with your loading habits and cycle preferences. By following the manufacturer’s guidance, you minimize residue and dosing errors.
Tip: If you’re unsure, start with tablets for consistent dosing and reliability. - 2
Assess water hardness and salt needs
Determine whether your area has hard water and whether your model has a salt reservoir. If you see mineral buildup or frequent spots, enabling salt and adjusting hardness settings can improve cleaning efficiency.
Tip: Run a quick water test or check your city’s water hardness rating to guide salt use. - 3
Decide on rinse aid usage
Rinse aid is especially helpful in hard water and for glassware. Ensure the dispenser is filled and setting is appropriate for your cycles.
Tip: Set the dispenser to a mid-to-high level if you notice spots on dishes. - 4
Load dishes for optimal cleaning
Load so that water can reach all surfaces; avoid overstuffing. Place bowls and plates at angles to maximize rinsing, and keep plastics on the top rack away from the spray arms if possible.
Tip: Angle items to allow water flow and avoid nesting. - 5
Select an appropriate cycle
Choose a cycle that matches soil level and load type. For everyday dishes, a normal or eco cycle is usually sufficient; for heavy soils, use a more intensive cycle.
Tip: Avoid short cycles for dirty pots and pans unless needed. - 6
Run the cycle and inspect results
After the cycle, inspect for clean dishes and check for any residue. If issues persist, re-run with adjusted detergent or rinse aid levels.
Tip: If residues persist, try a hotter wash or clean the filter and spray arms.
People Also Ask
What is the best detergent to use in a dishwasher?
There isn’t a universal best detergent. Choose a form (tablet, powder, or gel) that matches your dishwasher’s guidance, water hardness, and soil level. Consistency and following the label reliably deliver good results.
There isn’t a single best detergent; pick one that matches your dishwasher and water hardness, and use it consistently.
Do I need to use rinse aid every cycle?
Not every cycle is required, but rinse aid helps drying and reduces spots in hard water. Use it when you notice water spots or if your dishwasher has an adjustable rinse aid setting.
Not every cycle needs rinse aid, but use it when you have hard water or see spots.
Can I use regular dish soap in a dishwasher?
No. Regular dish soap foams excessively and can overflow, damage components, and leave residue. Always use dishwasher-approved detergents.
Don’t use regular dish soap in the dishwasher—it can create foam and damage the machine.
Is dishwasher salt the same as table salt?
No. Dishwasher salt is specifically formulated for water-softening systems in dishwashers and should be used only if your model requires it.
Dishwasher salt is designed for water softening and isn’t the same as regular table salt.
How often should I clean the dishwasher interior?
Clean the interior every 1–3 months or when you notice odors or residue. Use a dedicated dishwasher cleaner or run an empty hot cycle with a cleaner.
Clean the inside every couple of months or when you notice odors.
What’s the difference between pods and powder detergents?
Pods provide consistent dosing and convenience but may not dissolve well in cold water. Powder offers dose flexibility but can clump if exposed to moisture.
Pods are convenient; powders give you dose control, but both work when used correctly.
