Colored Clothes: 5 Mistakes That Ruin Colors (and How to Avoid Them)

Have you ever washed a red t-shirt only to find it faded, or worse, dyed your entire laundry load pink?It happens more often than you think. Colored garments are the most delicate to wash, and small everyday mistakes are enough to ruin colors that seemed permanent.

In this guide, we look at the 5 most common mistakes when washing colors — and how a laundry detergent specifically formulated for the job, like Sapo Colorati, can make all the difference.

1. Using a universal detergent

The first and most widespread mistake is washing colored items with the same detergent used for whites or mixed loads. Universal detergents often contain optical brighteners that aggressively attack pigments, causing progressive fading after every wash.

The solution:use a specific detergent for colored clothes that is free of optical brighteners and formulated to protect colors. Sapo Colorati is a 3x concentrated enzymatic liquid detergent designed exactly for this: to preserve the original shade and prevent color bleeding during the cycle.

2. Not separating items by color

Putting red, blue, and white clothes together in the washing machine is one of the most frequent causes of chromatic disasters. Fabrics release dye into hot water, and that dye ends up straight onto your other garments.

The solution:always separate your laundry by color intensity — darks with darks, lights with lights. For extra protection, Sapo Colorati actively blocks color transfer during the wash, reducing risks even in mixed loads.

3. Using water temperatures that are too high

Heat is the number one enemy of colored fabrics. Washing a garment at 60°C (140°F) when it only requires 30°C (86°F) will not only fade the color but can also shrink the fabric and damage the fibers.

The solution:always check the care label and prefer low-temperature cycles. Sapo Colorati is an enzymatic detergent: its enzymes work effectively even in cold water, guaranteeing a clean wash without having to turn up the heat.

4. Incorrect detergent dosage

Too much detergent does not mean cleaner clothes — it means residue on fabrics, insufficient rinsing, and, over time, dull colors. On the other hand, using too little will not clean properly.

La soluzione:the correct dosage depends on water hardness and soil level. Because Sapo Colorati is 3x concentrated, the required doses are very small:

Soil Level	Soft Water	Medium Water	Hard Water
Light soil	15 ml	20 ml	45 ml
Medium soil	30 ml	45 ml	—
Heavy soil	45 ml	60 ml	75 ml

Recommended doses are for a standard 4/5 kg (9/11 lbs) washing machine load, or for 10 liters of water when hand washing.

If you do not know the water hardness in your area, you can check it on your local water supplier’s website.

5. Ignoring hand washing for highly delicate items

Many delicate colored items — fine cottons, viscose, colored wool — suffer from the mechanical friction of the washing machine drum. This friction accelerates fading and alters the fabric structure.

The solution:for your most precious pieces, hand washing is always the safest choice. Sapo Colorati can also be used for hand washing: simply dissolve it in 10 liters of water and follow the same doses per soil level indicated above.

Why choose a refillable / “on tap” detergent

Sapo Colorati is availableon tap (via the Sapospina refill system): this means you can buy only the exact amount you need, reducing plastic waste and lowering costs compared to traditional packaging. A concentrated refillable detergent has a significantly lower environmental impact than single-use bottles — resulting in less plastic, less transport, and less packaging waste.

Frequently Asked Questions

Can Sapo Colorati be used on all colored fabrics?Yes, it is suitable for cotton, blended fibers, and garments washed either by machine or by hand. For highly delicate fabrics (silk, fine wool), always check the garment’s care label.

How many washes does this concentrated detergent yield compared to a traditional one?Since it is 3x concentrated, an equivalent amount yields approximately three times as many washes as a standard detergent.

Can I use it in cold water cycles?Yes. The enzymatic formula is effective even at low temperatures, making it ideal for 30°C (86°F) cycles.
