removal of resin

Dear Iacopo,
I have finally installed the hinoki tub in our house in Whistler, Canada. It looks really great. Before I start using it, I have a question about it. The wood surface of inside part of the tub produced a sticky sap. Is it normal and should I was them off before using it or leave the sap as part of the aromatherapy property of hinoki wood?
Sorry I never own one before so I am clueless.
Many thanks for your help,
G

Dear G
The bathroom looks great!
About the resin deposit: it is natural and of course it does not have any health implication.
You can remove it using a solvent as Acetone. You can purchase it at a paint shop or home center.

Be sure to keep the window open (as it is highly flammable), put some acetone on a cloth and wipe gently.
Please keep me updated on the result.
Best regards,

Happy new year to you!
Yes, the acetone worked well to remove the resin deposit.
Here are some other photos I took of the hinoki tub… feel free to use anyone.
