The Light Blues have once again hit the headlines for all the wrong reasons in recent days following the departure of chief executive Craig Mather as the boardroom battle intensifies.
Furious fans have staged a series of protests against the Ibrox hierarchy but skipper McCulloch is keeping his attentions focused on the field.
He said: "Since everything started, from administration on, the thing we've tried to do is keep the dressing room focused on playing football, trying to win games and let everything else sort itself out.
"The experienced ones have got together and we've basically said 'let's concentrate on winning games and everything else will be all right'.
"That's the only way to look at it, we've got to be positive and remember we have a responsibility to go out and play for the fans and ourselves.
"I think it would be easy to start looking for excuses and say, 'this is how I didn't play well'.
"But it's important to blank everything out and concentrate on playing football.
"I think most people long for the day when it's all sorted out but we're playing for our livelihoods and we need to be playing well.
"We've got to realise that the transfer ban's been lifted and we can all be replaced easily.
"Whether you're an experienced player or someone who's not long here, that's the stance we've taken."
Despite the ongoing troubles around the Ibrox top table, it has been an encouraging start to the season for Ally McCoist's side, who head to Brechin this afternoon aiming to record their ninth straight League One success.
McCulloch has sampled the highs and lows during his glittering Gers career and reckons his time in Scotland's lower leagues will stand him in good stead.
He said: "At times it gets hard when results don't go your way and you're getting criticised when you're not winning four, fives and sixes.
"But it's all a challenge and that's how you look at it.
"It's a challenge in the SPL but at a club where there's demands on you like there are here, when you drop down leagues there's a different challenge.
"It's great for experience to go through all types of scenarios with such a big club. It'll make the players and management stronger and better in the future.
"I include myself in that - the more things you experience the better it is for the future and the young boys in particular will benefit from that."
After leading his side to Third Division glory from the front last season, McCulloch has switched to a central defensive role this term.
And the 35-year-old admits he is relishing his new partnership with summer signing Bilel Mohsni.
He said: "I know he's getting compared with Bougherra. When I played with Bougherra I was in centre mid and anytime Bougherra would go on one of his crazy runs I'd to sit in for him.
"Now big Bilel likes breaking forward which is brilliant but sometimes I panic a bit about getting somebody to fill in. But he's done brilliantly, he's come in and scored goals as well.
"He's a really good player, we did well to keep hold of him and he's only going to get better."
