Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation as 'кислотная стирка' which sounds like washing *with* acid as a detergent. The standard term is 'кислотное травление' or 'эффект кислотного травления' for fashion, and 'кислотная промывка' for industrial contexts.
Common Mistakes
- Using 'acid wash' as a verb without the -ing (correct: 'to acid-wash' or 'the acid washing'); confusing it with 'stonewash' which uses pumice stones, not necessarily acid.

FAQ
Frequently Asked Questions
Yes, but less frequently due to environmental concerns and changing trends. It is often used to create specific vintage or retro styles.
Acid washing uses chemicals (acids/bleach) to remove dye. Stonewashing uses pumice stones in a washing machine to abrade the fabric; it may or may not involve chemicals.
Yes, traditional acid washing can be harmful due to the use of toxic chemicals like potassium permanganate and the resulting polluted wastewater, leading many manufacturers to seek safer alternatives.
It is not recommended due to the hazardous chemicals involved. Safer DIY methods for a similar look use diluted bleach or specific fabric dyes, but true industrial acid washing is a dangerous process.
