Ray's
Telescope and Optical Cleaning Services 
Luckily (touch wood) I haven't had any cleanliness issue since washing the primary mirror before mounting the scope in the new observatory way back in August 2014
...haven't adjusted the polar alignment or colimation either since then..still spot on after using the NJP Polar scope and a
rock solid pier 
Look forward to some even better
