hi all
i got told you can wax the shell to harden it is this true?????????

Hiya,

Definitely not. It will block the pores in the shell and atract dirt. The only thing that should be put on a tortoise's shell is water during bathing or if you need to rinse off the dirt or muck at any time.

HTH
Kindest Regards

i went to see some one i new who had a tortoise an he sad he maxed the shell i didnt think that was right

Definitely not right Jack:-)
We've had rehomers in whose shells were absolutely black from oil/wax and have absolutely ages to clean up:-(
