Skid Row were among the top-selling heavy metal bands of the 1980s and 1990s, scoring hits with '18 and Life', 'Youth Gone Wild' and 'I Remember You'.
Bach left the group in 1996, leading to Johnny Solinger becoming the current frontman for Skid Row.
Solinger recently raised objections when his predecessor first hinted at a reunion of the classic Skid Row lineup on Twitter, with Bach having now responded in a Facebook post.
"My little fingernail has forgotten about more attention it has received than my replacement will ever receive for his whole life's work," Bach wrote. "I answered a tweet from someone on my Twitter account with the response '4 out of five of us would reunite'. That was all. My one tweet made news the world over."
Bach went on to suggest that a reunion of the original Skid Row would be a nice tribute to the band's loyal fanbase.
He explained: "For the fans, I would be willing to put my ego aside and do something that would be special for the people who put us where we are today. I do not personally want it myself. It's not always about 'what I want'. If the fans really want to see us together, I would do it for the fans.
"Sometimes you can do things for people other than yourself... If [Skid Row] want to try and get out of the internet bulls**t and come together for the sake of the fans, you can give me a call."
The current incarnation of Skid Row have not yet responded to Bach's post, but the singer later removed his post from his Facebook page.
Bach has continued recording solo work since leaving Skid Row and also starred on the reality shows Supergroup and Gone Country.
