Cleaning my "Frogsville" pot

Hi, I understand that this may seem bonkers to some, but I like to clean anything I keep and need some advice as to whether what I intend to do is ok, or not.
The bowl (see below) is stoneware with sculpted figures. I intend to fully submerge it in soapy water, gently scrubbing between bits with a toothbrush.
I intend to dry it gently by hand as best as I can and then finish the process by placing it in the oven for an hour or so, on a very low heat.

Is this ok ?

Thank you in advance for your comments.

Welcome to the forum. I’ll move this to the General Pottery Discussion group as it’s a general cleaning question rather than a specific potter or pottery

Ok Naomi, thank you.

First question.
Why clean it? Part of the attraction of old pottery is the natural accretions of age and time. They add character and indeed provenance, cos a lot of people like the signs of age on old pottery. Brand spanking sparkling new like it was made five minutes ago is actually a serious turn-off for many collectors.
If you Really,Really HAVE TO clean it.(WHY!!!!). Then start gentle and work upwards. Warm water soaking, and then rinsing in cold water. If you are not satisfied with that, step upwards, using the gentlest cleaners you can find. Tooth brushes? mmmmm… Not too sure there. Those bristles on new ones can be quite harsh. There look some quite fragile pieces in that piece.
Gentle, gentle does it....

and the oven is not really necessary

Lol, I know it seems extreme, but I am really ocd . Though not as bad as I used to be, I still like to clean things once thoroughly and then just give them a dust every couple of weeks.
The toothbrush is a really old soft one that I use for dusting out fiddly bits, so am confident that can cause no harm.
I do not know how old it is, though I bought it very recently, and am certain that I will never sell it, so am not wanting it to gather dust and look old.
I really do want to submerge it, but only for a short while with a dash of ecover. Surely this will be ok?
Thanks for your response Phil, tis appreciated.

Thanks Dan, but I just want to ensure it is completely dry. Isn't that important?

a hair dryer or leaving it out on a sunny day would be my method of drying but it's ceramic so drying is not important at all

Thanks Dan, I think I'll let the sunshine deal with it.

At terrestrial auctions, you will find that Nothing has been cleaned.
There is a reason!

but if you intend to keep it for yourself then clean away

I remember my parents had a lovely collection of delicate Lladro. My Dad used to 'clean' them regularly with a feather duster. There were a number of missing fingers!

so cleaning can have positive results

Thanks folks, though I have decided to tone it down a bit and not fully submerge it.
My greatest concern was to some of the unglazed areas under the frogs, I wondered if water may get in and cause fractures of some sort over time. One of my first purchases was a Moorcroft vase from their natural pottery range, after a wash it made crackling noises for at least a week or more after, so to do the same with this bowl and have a similar result would make me a little nervy.
