If a given number is not a palindrome, reverse its digits and add the new number to the original number. Repeat until you have a palindrome. Let's take 185 as an example.

185 is not a palindrome
185 + 581 = 766, which is not a palindrome
766 + 667 = 1433, which is not a palindrome
1433 + 3341 = 4774, which is a palindrome

I don't believe any generalized method is available. The squares of any whole number with all digits being one (such as 11, 111, 1111,...) are palindromes but certainly do not produce all palindromes.
