However, you could try using these words which have similar sounds or end with similar syllables:
* लोहा (loha) - This word means "iron" and rhymes with "धोना (dhona)".
* सोना (sona) - This word means "gold" and also rhymes with "धोना (dhona)".
While these aren't directly related to "washing clothes", you could use them in a poetic context to create a rhyme scheme.
It's important to note that Hindi rhyming is often more flexible than English, and finding a perfect rhyme might not be possible.
