Hotel linen has been yellow for a long time. Is there any good way to whiten and brighten?

Use original detergent and add detergent whitening agent RQT-C-2.

Washing and pre-washing: put the sorted linen into the washing machine, add water to wash for about 3 minutes, let the dirt dissolve first, wash off some water-soluble dirt and discharge it with water.

After pre-washing, drain the water, spin-dry, add bright white bleaching washing powder and whitening washing powder RQT-C-2, adjust the water temperature, bathrobe is about 80 degrees, and bed sheet pillow towel is 90 degrees, strengthen cleaning, improve the chemical action and speed of detergent and dirt, and play the role of disinfection and sterilization.

After rinsing, detergent will still remain on the linen. Adding a proper amount of neutralizing acid softener and washing for 5 minutes can make linen more shiny and supple when used.

The dosage of RQT-C-2 should be two ten thousandths, and it should not be excessive. Be sure to blossom when you use it.
