There are many types of product attributes like text, dropdown, yes/no, text swatch, visual swatch, etc. There is only one function to remove any type of product attribute. In this blog, we get an idea of how to remove product attributes using a data patch. The following snippet is a full code example of a data patch to remove product attributes.

<?php

declare(strict_types=1);

namespace Mage2\Demo\Setup\Patch\Data;

use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Framework\Setup\Patch\DataPatchInterface;
use Magento\Catalog\Model\Product;
use Psr\Log\LoggerInterface;

class RemoveDropdownProductAttribute implements DataPatchInterface
{
    /**
     * @var ModuleDataSetupInterface
     */
    private ModuleDataSetupInterface $moduleDataSetup;

    /**
     * @var EavSetupFactory
     */
    private EavSetupFactory $eavSetupFactory;

    /**
     * @var LoggerInterface
     */
    private LoggerInterface $logger;

    /**
     * @param ModuleDataSetupInterface $moduleDataSetup
     * @param EavSetupFactory $eavSetupFactory
     * @param LoggerInterface $logger
     */
    public function __construct(
        ModuleDataSetupInterface $moduleDataSetup,
        EavSetupFactory $eavSetupFactory,
        LoggerInterface $logger
    ) {
        $this->moduleDataSetup = $moduleDataSetup;
        $this->eavSetupFactory = $eavSetupFactory;
        $this->logger = $logger;
    }

    /**
     * @return void
     */
    public function apply()
    {
        try {
            /** @var EavSetup $eavSetup */
            $eavSetup = $this->eavSetupFactory->create(['setup' => $this->moduleDataSetup]);

            $eavSetup->removeAttribute(Product::ENTITY, 'sample_dropdown_attribute');

        } catch (\Exception $e) {
            $this->logger->critical($e);
        }
    }

    /**
     * @return array
     */
    public static function getDependencies()
    {
        return [];
    }

    /**
     * @return array
     */
    public function getAliases()
    {
        return [];
    }
}

After that, we need to run the following command in the command line interface:
bin/magento setup:upgrade

This data patch would completely remove any type of product attributes and their related attribute options.
