Hello,
You can translate/rewrite all theme and plugin texts via PO file in WordPress. Here is a video tutorial that should help you translate your website texts with a Loco Translate plugin https://www.youtube.com/watch?v=D3NsDdMzsls&list=PLMw6W4rAaOgKKv0oexGHzpWBg1imvrval&index=3
Please check the video tutorial to see how to save the translation file correctly. You can remove the plugin and translations would remain. Also, translations would remain after each theme update.
In order to translate the WooCommerce strings, you need to create a separate translation in Loco > Plugins > WooCommerce in the same way as shown in the video.
Description – is the main description on the product page. If you clean the product description it would disappear.
Reviews are disabled in the Woocommerce > Settings > Product.
Additional tab (with the attributes) enter each attribute in the product page and disable showing on the product page to hide the tab.
Additional tab (Shipping information) You can edit it in the Theme Settings > Product page > Tabs > Additional tab Clean all the content.
If you have any questions please feel free to contact us.
Best Regards
