If You check out Your home builders store You may find fid some purer paraffin oil. Its often used for wood care. I have used it for a long time on my wooden cutting boards. Its good for this, because its taste and odorless.
Then You can use white spirit (also made from petroleum) to make it thinner if You want.
But in the end its really destroying the sponge...

I have been pretty happy with Haifu Seamoon and Falco Temp Long.
I am just going to try pure baby oil = mineral oil and see how it goes this time.
I have tried Haifu National Yellow before and did not feel that it was worth the cost.
I have gone back and forth between Haifu Seamoon and Falco temp Long, and I do not believe that Falco tempo Long really lasts "longer."
I think it is all marketing.
I do believe that once boosted, the sponge is permanently changed. Some people say the effects of booster go away within 2 weeks or so. Quite honestly I cannot feel the difference. I often wait for 3-6 months before reboosting the rubber again. I don't have time to reboost rubbers every 2 weeks.
