I've been doing this over 20 year's and this is my situation. A Breakfast restaurant that I've cleaned twice so far has a good quality carpet, the problem is the grease that gets thick enough that looking at it you can see the layers of greasy sheen.
I'm using a very good enzyme with hot water which cleans up great, dwell time not an issue. I have a Prochem Apex which get hot, 220 easy.
So I decided to break out the 175 rpm and a red pad. The pad cleaned the carpet well but did not cut into the greasy layer, basically just glided over it.

What would be the next pad the will bite a little more but not damage the carpet?

Thanks

Have you tried a CRB instead ? It digs downwards into the carpet fibres

Are you using a long “dwell”
