That’s clearly 33.333 RPM. note the gap between the first two frazps.
The problem is probably damaged vinyl and no amount of cleaning is going to help.
You might have some success with “clickrepair”. This is not-free software, but it does decent job of cleaning up noise on old LPs. You will likely end up repairing the worst of the frazps manually. Click-repair has a manual mode you can use, or there is another not-free but not horribly expensive program called wave-repair you might want to try as well. Wave repair also has features that streamline the task of breaking albums into separate recordings that IMHO are easier and quicker that the same task in Audacity.
